For some unknown reason the level 1 ooze summon "Small Ochre Jelly" seems unable to move. It has a movement speed decrease applied to it, I'm not sure if that has something to do with it or not.
I've tried the follow and attack nearest commands, as well as using the Control Companion tool, but I've been unable to get them to move.
They do fight anything that comes into their range though.
Its meant to be stationary. Albeit it makes it useless for anything other than luring mobs which is a bit against the rules at any rate. Could use a revision methinks.
The ooze has a very specific use and fits such well, it is intentional! And has been like that for quite a while. So I doubt it will be changed any time soon.
No bug.
