Observe this screenshot from my ongoing Campaign Peninsula: Savage's Station (05g) game:

See the Union (11th Maine, in line) and "Confederate" (2nd Co/Mass. SS, in column) units sharing the same hex (due south of the "Chickahominy River" label)?

I have been playing through the Seven Days Battles and have seen anomalies like this more than once.  IIRC, I have seen these occasionally in other HPS/JTS American Civil War games also.  (Note:  This is not an artifact of the graphics mod I use.  It's there, too, in the default unit images, AFAIK.  This is an OOB database problem, I believe.)

Has anybody else seen these glitches?  Catalogued them?  Fixed them?  If so, how?  (In the Scenario Editor, not by mucking with the images themselves.)

I try not to let it bother me too much (mostly play in 2D; switch to 3D for firing and meleeing, typically at maximum zoom out; so usually don't notice it) -- but it does undermine the immersiveness, just a little.

You sure that's not a graphics mod problem.  I've been playing all the HPS games since the Corinth came out in the day and never seen that.

Yup, pretty sure it's not a graphics mod problem.  Here is (essentially) the same screenshot, with the standard default graphics:

It's not quite as apparent, because the default graphics lack flags; but the Union unit in line (2nd Co/Mass. SS) sure looks like they're wearing Confederate gray, no?

I recall seeing this very same anomaly in the Seven Pines scenario about a year ago.  I investigated, and IIRC, the glitch might have something to do with the SS units.  I wasn't able to figure exactly what the problem was, but I inferred it's an OOB data problem.  As I think I've demonstrated, the glitch manifests itself across more than one graphics set.

BTW, I won't bother to display it, but the Union 2nd Co/Mass. SS wearing Confederate gray (and in the mod, waving the Stars & Bars) shows also in 3D zoom out mode, with both my preferred graphics mod as well as the default HPS/JTS graphics.

"Ah ha!" you might say, "You are using the Old Banshee graphics mod package [which replaces the standard OOB files with a revised Old Banshee version(s)].  There's the problem."  Maybe, but I recall seeing the Union-wearing-Confederate-gray a year ago, before I installed the Old Banshee Campaign Peninsula package (and even before Old Banshee made it available?).  It could be a problem with the Old Banshee OOB file, but I doubt it.

If anybody cares to look into this (in particular, the Old Banshee team), that would be great.  Otherwise, I'll just continue to ignore it (for the most part).

Another instance of this glitch, this time involving Brady's Co/Mich SS (first with my modded graphics, then the standard default graphics set):

I also see (but not displayed here) that elsewhere on the game map, the Union 1st-2nd/Mass-Minn SS are wearing Confederate gray (and waving the Stars & Bars).

This seems to confirm that the problem is related to SS units (and also?).

However, when I inspect other Union SS units around the map, I see at least two -- Berdan's S.S. (1/1st U.S.S.S. & 3/1st U.S.S.S.) -- that are rightly and properly blue (actually green; and waving the Stars & Stripes).

So, the problem sure seems real.

(Curiously:  In the last screenshot above, the routed Union units by the Chickahominy River are wearing the Confederate Gray -- with the standard default graphics.  But in the screenshot preceding, they're wearing the Union blue, and waving the Stars & Stripes.)

As a test, I went back to my archived, unpatched CD install.  I didn't do a thorough search, but I did not see any problem with the 2nd Co/Mass. SS (shown in the OP).  So, the problem was introduced somewhere between the CD version and the current patched version.

Again, this might be a problem with the Old Banshee OOB file(s), but I tend to think maybe not.

???

Enough.  Back to playing!

It is a little odd, to talk about stock graphics, official patches, then lob in using what is a modified OOB (mind you the OOB's in the Civil War series are locked- so getting them from anywhere other -in this case, HPS, in effect "you takes yer chances", as the guys that made those OOBs are messing with things not intended to be messed with at this point -no matter what they say.

Ok, all that aside, the only way to actually test if it is their OOB is to only use the stock OOBs. The OOBs which in effect are structured in the same way as other titles which are editable. The OOB files call graphics from specific locations on the BMP files; if the OOB file is botched; or customized in such a way that it is calling its own set of graphics (which is, as I understand things, the sole reason that that particular set of mods add an OOB file - to call graphics from additional areas of the BMP files... ). If you use standard graphics with an OOB file that is calling something from somewhere else - then, bingo -you get something weird.

Of course, just stating "but I tend to think not" - is hardly analytical enough for anyone to get any idea as to why it is that you think otherwise. 

My advice, ditch the alternate OOBs to eliminate that as a possibility, then try it again.

I installed Campaign Peninsula on another system, then applied the latest official patch.  No other mods--Old Banshee, custom graphics, or otherwise.  Looking around, I don't observe the anomalies.  The problem is somewhere in the mods I use and/or their interaction.

Since I mainly play in 2D mode, at this point I don't care to investigate any further.  I'll just continue to live with it, and ignore the minor annoyance.

Sorry for the trouble.

Those 3d graphics of the men in this title don't look too bad. I could stomach similar if it was in the Napoleonics. Sadly, I think I might be whispering this wish into the wind....
