Invisable bug

[Wanderinsamurai]

Im not sure is this a glitch or not but today i was in a pking game and a necro mancer with a belt full of mana pots was nking me and this zon,the necro made bone prison all over the entrance to town once something break the necromancer casts more.The necro said "Im gonna try to lagg you guys until you guys drop out" so he continued to nk us and make bone prisons.Then the necromancer made a bunch of golems on n off so there clay golem corspe on the floor. After that the necromancer left the game and then the gay started acting funny,the zon that was in my party casted a decoy on a clay golems corspe n the zon became invisable off n on and when i charge i turned invisable off n on too.

I was wondering could this bug dupe or something
well? can it?
