tested modlist

Baubles-1.12-1.5.2.jar

extrautils2-1.12-1.7.5.jar
Forgelin-1.6.0.jar

@Buuz135

I think its a KleeSlabs issue because that happens when checking if a block can be broken or is protected by protection mods. Maybe KleeSlabs can filter fake players?

NOTE:

this will not happen with

KleeSlabs_1.12-5.3.2.jar

Thanks @blay09 !
