In creative, for an unknown reason, people can place —but not remove— heads and banners in other people's plots. Is there any solution? Thanks! I'm writing this post here as I can't find any Bug Report subforum or anything like that... xD Thanks to Rana_Crafting for telling me about this bug c:
This is probably a glitch with the plots plugin. Also, about the second bit, this ought to have been put in the Help section. @Admin can move it there and take a look at the issue with @BlueFusion12, hopefully.
This is a bug. However this bugs allows you place some things on any plot. We do not know the cause yet however we are looking into it. For now please do not use this bug at all to grief other wise we do need to punish as it counts as griefing. Things will be fixed soon Any further questions feel free to ask.
