Hey Mylon,
a user of my modpack (https://forums.factorio.com/viewtopic.php?f=96&t=24889) reported massive UPS drops with your mod. He uploaded a savegame (https://www.dropbox.com/sh/09shu264stdif8q/AABfOf9o8JBKs27YydohOHe0a?dl=0) so I could see for myself. 2-3 seconds after loading the savegame, the script time of GlobalWarming goes up to 50+, which makes the game a lag fest. It stops when the water also stops expanding. I hope you can help.
I'm going to have to switch to maintaining a table of potential chunks. The current method of finding shore tiles is very inefficient. It'll take some time to test it out but it needs to be done.
Updated with a new method! Performance is improved.
