Whenever i try to place anything near my fluid inputs or try to remove/change them i get this crash.

Does this happen with every factory building, or are some buildings unaffected (for example some you just recently placed)? Does this happen in a fresh world (using sandbox mode)? Does the crash still happen after you pick up and replace your factory building?

Please also provide your save file, or describe a way for me to reproduce this crash from scratch, including which mods you use.

Just replacing the factory seemed to fix it, not sure how to reproduce it since ive had this save for a long time and it only just happened recently without me changing anything. My guess is that one of the newer factorio versions broke something

I'm glad the issue went away by itself, but if you do find out how it happened, or if you have a better idea what particular mod/version changes could have caused this, let me know.
