Before I start, I am using a small mod with the Gameplay.constants that only increases build/income rates and fleet sizes. I have used much more complex mods with that file in the recent past with no problems, even during beta.
The problem: I seemed to have run into a wall while playing entrenchment. Whenever my games reach what appears to be a certain point, it crashes. I can't figure out why, but it happens at the exact same moment everytime (and I can't figure out why). So far it's only happened with TEC (haven't gotten around to playing with the other races.)
I have both a reproducable CTD save (wait roughly 5 minutes normal speed) and a minidump as well, but I do not remember the email for support.
[EDIT] Update! Got an email back from support, and it was sort of my mod. The mod I was using allowed for much larger fleet sizes, and I was running out of RAM, which crashed the game. Heh, funny thing was that the game could handle it, but my system couldn't LOL!
