For issues:

Important Information

Describe the bug
https://mclo.gs/pwWOLkG

To Reproduce
install create 6.0.1 and dramatic doors together

Expected behavior
A clear and concise description of what you expected to happen.
not to crash!!!

I will have to look into fixing, thanks for reporting!

It also should be noted that the issue isn't on 1.21.1 as Create compat was removed temporarily, due to Create for 1.21.1 having not existed back then.

I will work on a compatibility fix for 1.20.1.

Came on here to report exactly the same thing.

I was having the same issue, but I did figure out if this information is helpful to anyone

That version: DramaticDoors-QuiFabrge-1.20.1-3.1.0_1.jar - works with the current newest version of: Create 6.0.2 for mc1.20.1
and on the other hand
The newest version currently works of: DramaticDoors-QuiFabrge-1.20.1-3.2.9_1.jar works with a later version of: Create 1.20.1 0.5.1j

Here are the latest.log errors mentioning DramticDoors if that helps debugging.

I have also been experiencing this issue.

The new version of Dramatic Doors is being uploaded to fix compatiblity!

So far, it will be just for Forge as Create Fabric 6.0 is not yet publicly released.
