i believe thats caused by the 81 tile mod,, i had the same problem,, still cant use it even if the author says its fixed,, remove the 81 tile mod and those error messages should disappear

[MaximusSupremus]

hey , is there another alt to get all 81 tiles that you know of ?

[MarkJohnson]

81-tiles is fine and works great.

Some other mod is conflicting with it.

Maybe check the mod page to see if any are listed in the description or comments.

Which version of 81 Tiles are you using?
