## About The Pull Request ai controllers that have exhausted all their current behaviors now stop processing until the next cycle, so we no longer need to do these checks on every process fire. idle behaviors are now instead handled by a new low priority subsystem. these are the costs before/after roughly 25 minutes into the round  ## Why It's Good For The Game improves ai performance ## Changelog 🆑 /🆑
