I know this has been reported by another player...but just wanted to add it happened to me also.
Second mission in the campaign, I won, with 2 killed, 2 wounded and 3 missing...but more strange than that, I killed 2 enemy soldiers...and there were none left alive...so the entire enemy consisted of 2 soldiers???
It may not be a bug ...but thought I'd better tell you anyway.
In reply to that posters message, you said you'd deal with it in another thread. The other thread (or "a"nother thread) I noticed you said there had been some campaign tweaks, but for those downloading on Sunday, it wouldn't be a problem as the download would already include the updated campaign file for whatever changes you made...well I downloaded on Sunday, so if your "campaign edits" had anything to do with this issue, I don't have the fix.
