OOS error in BTS v302

[bolt144]

OOS error while playing BTS. 2 players both at v302 - 6 AI's, Direct IP, turn based, epic, standard game, fractal map. We played for about 2 hours until this error first appeared and did not resume (we will try again later in the week). The host player was in one of the diplomacy screens (I think) when the other player ended his turn. An autosave is attached from before the crash. I didn't have any logging enabled as I wasn't expecting this. Will enable logging for next time.
