Well, I let my veggy sim run overnight to test some of the new mutation routines. There were only 30 alga minimalis, and they were getting food by kilobody, so they couldn't just reproduce madly to get any more energy.
I woke up and went to check on my sim. Turns out at least one of the little buggers learned to shoot -1 shots. Also managed to crash the program, which is good, because I'm determined to find any and all bugs.
He also is managing to gather energy from nothing, which is deeply disturbing.
