Hi. It seems like the "creative-mod" is signaling that an entity is restored but it is not giving this entity a force. While it is quite easy to fix so that it my mod wouldn't crash when this is happening, it would lead to other unexpected issues - the restored GUI Signal Display would not be connected to a force and therefore unusable.

Honestly, I consider this to be more of a bug with the "creative-mod". When using the undo functionality that you mention, it should use the appropriate force.

Ok, thanks. I'll cross post. Should have done that immediately probably q:

Hi!
I'm the current maintainer of the creative-mod mod :P
Thanks for reporting this bug.
I've pushed a new bugfix release v1.1.4 for the "Creative Mod" which should fix this error.
Have fun! :)

Thanks! <3

I guess I should have crossposted this a month ago! q:
