I can only assume it's due to the latest patch, but my save is suddenly tanked to ~30-45 UPS.

Took a glance at the code and it looks like you have this new "friendly biter controlling" feature running on every tick, doing some full-surface searches for characters every tick is going to be very expensive.

Suggested fix would either be tracking which surface(s) have active characters (though that is susceptible to cache issues) and/or running that code much less often (though that may result in choppy UPS spikes instead of constant lag).

Hey! Thanks for the report. I also appreciate the suggested fixes!

This wasn't addressed in today's update v0.0.51025, but it will be addressed in the next update (v0.0.51026) which I plan to have ready either later today or sometime this weekend. I'll likely do some kind of character tracking/surface caching.

I apologize for the inconvenience and appreciate your patience! Let me know if v0.0.51025 changes anything haha

I've pushed another update (v0.0.51026) that should reduce this lag significantly.

Happy to report that this has indeed fixed the issue. Script time for the mod went from 24ms+ all the way down to 0.3ms :)
