[Druid]

Do you mean you have a script on the server which spawns somethin only you can see?
I spawned several things into different maps and can't figure out what would meke it were your the only one who sees it.
Is there any chance you also have the mod on your computer at the same time? If a copy of the mod was still on your server from testing it. There is a chance that what you are seeing is from the mod still on your computer and no the server.
