wow weird coincidence.. i was playing around in Swamp near the Gnome Threshold. I was lagging really badly which kinda allowed me to get past the fences. Anyway, i got inside the cave and i pulled some levers and ****. I got disconnect or probably got kicked off the server for being off map because when i came back i was in the unstuck me point. Anyway, i tried getting back in the cave but this weird thing happened. THERE WERE PURPLE SLIMES.
I asked people about it and they said the slimes were still green, SO IM ASSUMING THAT IT ONLY SHOWS ON MY SCREEN AND THAT IT WAS CAUSED BY THE LEVERS THAT I PULLED IN THE CAVE.
EDIT:
if this was suppose to be a quest thing.. feel free to delete my post. i dont want to spoil it for everyone.
