thank you for better explanation. I'm not sure if I can test it in short period of time, but certianly will use it in future.
S4P-RalphsModdedAricsMod097.zip from the page, everything is installed in right directories and works when this mod is not installed. unless there is a different version I'm unaware of, the mod. You can reproduce it by applying the file to fresh install.
it doesn't show errors when opening the game, only when loading and starting the new game. I think it's not being properly applying to mansion.gd
before and after installing the mod
