Normally when I have seen a performance drop I will see evidence of my computer working hard, but not this time. I have only seen Performance drops while playing gradually as I build bigger or more quickly if I send lots of bots to build/deconstruct.

While playing I noticed a huge fps/ups drop from around 60 down to 10. I had not built anything new or made any new big requests from bots. I loaded an autosave pre ups/fps drop and have recreated the problem without adding anything new. I have watched as the ups/fps drop without me doing anything. According to Activity monitor I still have plenty of ram and processing power so I am unsure what is causing the drop. I have included below both saves and screenshots before and after the drop.

The root issue is this:
Many many eggs are spoiling and the biters are trying to find a way to *get away* from the little island they're on but are constantly stuck due to being on water/blocked by chests on land. This causes them to use a lot of time trying to figure a way out.

Thank you for the quick response. that does seem to be the problem i will work on a fix
