Getting this error when using a drawer puller on an empty drawer. I get a similar issue when the drawer has more than 99 items
The game crashed: saving entity nbt
Error: java.lang.IllegalStateException: Value must be within range [1;99]: 0; Item must not be minecraft:air

My versions is 1.21.1 and I am using the create mod as well

Fixed this last night for 1.21.8 but good to know it goes back to 1.21.1 .. should have a fix for it in the next release

Sounds good. Thank you very much for the response.

Fixed in the latest 1.21.1 release, still need to release on other supported versions
