Turn 135 and I just hacked into a system to retrieve a sleeper. Problem is the game says one doesn't exist but clearly it does:

Unable to advance game because it hangs after selecting anything. This is getting really annoying as almost every game I've played somewhere between turn 110-140 the game will hang and you cannot continue anymore using the Penumbra expansion. At turn 133 the game started acting up and I could not move any units anywhere - you would select them and then try to right click and no direction arrow would appear. I quit and reloaded and that solved that problem but then at turn 135 I got this problem.

This has signs of either a null pointer and/or running out of memory.
