  • Fixed memory leaks causing gradual degradation over long sessions

  • Fixed various death/spawn lifecycle edge cases that could cause errors

  • Performance improvements:

  • Significantly reduced CPU cost of slime mold networks at scale

  • Fixed GPU upload path running at full cost every frame
