Whenever I switch from one battle plan to another from the Strategy Center in the mid to late game it always causes the game to crash.
EDIT: Here is a replay (NOTE: Download Jie's Critical Situation map first to view replay)
EDIT: Another replay on map Burning Crusade with the same circumstances(all upgrades, same GPs unlocked, crash in late game, etc.)

Replays perhaps?

Not sure how it's possible, since I can only save replay when the score screen appears after a game when winnning/losing or when exiting. The crash happens in the middle of a game.

The game automatically saves the latest match as a replay until you played a new one.

I never knew that before, thanks for the info. I put a replay up as soon as I can.
EDIT: Replay is up, I had all upgrades researched, my GPs was Armored Company. Covert Forces. R2 Carpet Bombing, Spectre Gunship, Guardian Angel, and Air Mobility. Crash from changing battle plans does not happen early game but mid to late when I have a large army. The crash usually happened to me multiple times on these occasions.
