Leaving this comment for the mod author: I looked at our mods and found that this mod changes a value that Dectorio fixes relies on to nil. Normally it's not an issue because Dectorio fixes will load before this mod but once my mod is added it will pull Dectorio fixes further down the load order, making it read a nil value. Either Dectorio fixes needs a nil check or this mod needs Dectorio fixes as an optional dependency.

Oh thanks for investigating this! I never got around to it. Adding an optional dependency is no problem if that's all that's needed.

I didn't test if any issues arise in-game, but I don't expect anything game-breaking based on the code I saw. I suspect this mod will modify the Dectorio fork's walls as it does vanilla walls this way, which IDK if it is a problem or not.

Actually I see the original Dectorio is a dependency too, so I'm guessing that should work just fine then.
