I am using file [snowyspirit-1.19.2-2.0.12] with Forge 43.2.0 and there are no sleds anywhere in the mod.

I have no clue. Must be a mod conflict as in my pack it doesn't happen

Sorry, my bad, they appeared after installing the supplementaries mod. I thought supplementaries was optional.

It is optional

Can you check if latest version works?

There are still no sleds without the Supplementaries mod in the latest version of the mod snowyspirit-1.19.2-2.0.14

This is with Supplementaries

And this is without

Fixed
