close to it, almost right beside it.. i even restarted the game and it still did it

Maybe that's the problem, since the potion will effect anything within range. Try the potion away from any other actors.

Edit:

Next update, I will make the potion turn every type of actor into a phoenix.

Edit 2:
Besides doors.

That would actually make for a great security system. I think. But I don't know how the door would react, so

Too many gibs

Does the potion retain pinning?
If not, the door will just fall immediately as well as just sort of waggle around in the gibs. If you stand on it, it'd probably dig pretty far too.

It does retain pinning, so you'll have a functional phoenix door. If I allow it.

Shouldn't be that hard to appropriate, but I use it more for fun insanity. I can't go insane on some robots with a door, now can I?
