Describe the bug
The doors are duplicated, tall grass are duplicated and the snow is acting weird

this started happens only in the last version of indium.

no. only with indium. with sodium works fine.

Does this occur without Indium but with Sodium?

I'm inclined to believe this is not a problem Indium can fix. Physics Mod is closed-source so it's hard for me to debug what is causing this problem, and it seems to make a lot of invasive patches to other mods - I suggest asking the author of Physics Mod to look into it. Reopen this issue if you know specifically what Indium needs to change in order to be compatible.
