[ARCHIVED] Can't make changes to build

So i downloaded some mods (that ive had before) and

everything was fine at first but then I tried to build and

after placing a few items they would place anymore.

The only thing i could do was moving around and

pressing esc to get rid of the item. I removed a mod

that I believed to be broken amd possibly the cause for

this. I uninstalled the game and restarted my computer

but nothing worked. When I try to save itll save forever

until I forcibly shut down the game. ldk what to do i

really want to play but there's not much I can do ☹️
