IGN: Cake_Squid Server: Creative 2, most likely all creative. Desc: I was trying to reset my plot (I am positive I was above my plot) but I got an error saying itcouldn't be done.
If Chase or CakeSquid Idea didn't work, try /plotme dispose. Then do /plotme claim(or /plotme auto if you want a new plot) and it should be all working again! :) Hope your question got answered. :)
