Again this season pet is not picking up items, very annoying theme 
The Altar sometimes dissappears (seems to happen on EU mainly), in that case the season theme and all Altar related things, including pets picking up items doesn’t work.
If it happens again, check Act 1 to see if the Altar is there, if it isn’t Leave game and start a new one, it should be back.
Repeat until it is there (IOW - sometimes only one reset may not be enough).
thanks mate, will check it every time. Starting now
