Is any error logged in warnings.txt? C:\Users\NAME\Documents\my games\company of heroes 2\warnings.log
Have you tried the 'rebuild' option in the mod builder?
This is it. The warning log i was talking about in above post is from unmoded game i played last night. I just try rebuilt the mod with 64bit atrib, game crashed but this time warning log point out that an epbs file failed to load. I removed that exact file and now i can built with 64bit atrib again.
It sound simple but that was a British medic model armed with rifle i created long ago but no longer use, i dont event remember it exist until you mention warning log and i kind of rediscover it.
Thank you, snake, now i can do modding and playing vanila without having to verify game file for atrib every time which is very inconvenience.
