I figured it out after using the debug “make dirty” cheat on the countertops and placing the dirty ones on every wall so that they could try and clean them one by one to tell me which ones wouldn’t work. Ended up realizing that two of the four walls in that kitchen won’t function if I put a countertop there. I ended up changing up the floor plan and widening the kitchen (which looks worse now but oh well at least it’s functional) and placing the countertops on the opposite wall and it worked no problem. No clue why nothing will work against that wall specifically. Like I said i’ve built a bunch of tiny houses and have never had this issue before, what could have caused it?
