Furniture Expanded 1.1-1.20.1 Fabric
There's a conflict with "Macaw's Furniture 3.2.1" mod

Sorry, I could only post a screenshot

As I don't have access to the other mod source code, all I can do is speculate what it is trying to do.

Anyways, I added a check before trying to access the trashcan tile entity, so in theory it should fix the problem. Can you try it out?

Don't forget to unzip it.

Unfortunately, I was unable ro recreate the issue with the older version of the mod to check if the new one actually solves it. But I updated it just in case.
I will post here if the problem happens again in the future.
Thank you!

Thank you for letting me know about it.
I'm glad that this is not a recurring problem, so i'll postpone this hopefully "fix" for the next release.

For now, I'll be marking this as solved.
