Pathing Invisible/Disappearing Mobs in Overthere

[SprinklesAK]

This issue may not be specific to Overthere, but it is the only zone I have observed it in. This appears to be new since the latest patch as well.

Mobs when stationary will sometimes turn invisible/disappear in OT, they seem to stay in the same spot however. If they are targeted already I can cast on them and as soon as they start moving they become visible again. If they start pathing again on their own they seem to reappear as well.

I seem to run into these invisible mob landmines a lot more lately in OT.
