US entered war early in 1916. In Aug. 1917 a US heavy artillery brigade showed up on Central Powers side - I thought it might have been captured in heavy fighting around Regensburg so wasn't concerned, but was surprised it showed as a US icon. The next turn about 6 or more US icon supply units showed up on the Central Powers side at Leipzig, and now I think are located at Halle. I've attached the [ATTACH]32693[/ATTACH] main log file but any .hst files I try get 'invalid file' error.
I also have been getting a lot of critical error crashes, maybe every 3rd turn or so. I've put full debug on now to try to get better data for you.
