I play my first game ever with BBAI (and 3.19) and jdog just leaves, meaning I might not get an answer for weeks.
I'm playing a game on a standard-sized map using the Tectonics mapscript. I'm at turn 250 or so now and I occassionaly run into
Memory Allocation Failures when trying to load a saved game while already in the game. Never before in these four Civ4 years have I experienced a MAF. I thought MAFs were caused by playing with heavy graphics or huge sized maps.

But BBAI doesn't have that. My laptop has 1.3 GHz processor and 2 GB RAM for the record.
Also I'm wondering if the following are normal:
The AI spends more time than in unmodded Civ in between turns. I guess that's to be expected for a better AI mod.
But also it takes much longer to load a game, more particularly the first phase 'Initializing'. Save file size at turn 250 is 750kb. This also seems much larger than usual, but I could be wrong: I don't usually pay that much attention to save file size.
I'd love to include BBAI in Planetfall, but not if it's gonna cause frequent MAFs.
