Priest Thrall Game Bug

Game mode: Online PvE
Problem: Bug
Region: [EU]

I’ve just noticed a game bug while playing on my online server.

I had a Priest Thrall praying at my god alter and I’ve just upgraded my alter to a sanctuary.

Now the Thrall has disappeared, his not visible anymore!

His still in the alter and his suppose to be there but just can’t see him anymore.

I tried taking him out and putting back in, I tried relogging and I’ve also tried restarting my server and his still not visible!

I hope this can get fixed soon!

same bug on PC official servers. Just upgraded to sanctuary of mitra and the high priest is no longer shown.
