Nope! I don't think it was even researched yet. I just played for 37 cycles straight (0 to 37) without making any manual saves or closing the game. There is a chance it was caused by the memory leak problem (I was unaware of at the moment). The game didn't crash again like that but I didn't play for more than 10-20 cycles. I posted some saves of that colony on another bug report about memory leak if you would like to check them.

That sounds very likely. We're investigating the memory leak right now and once it's fixed please let me know if it happens again.
