I've got the Playonmac version for feral heart and for a while it'll be going alright, then I'll crash. Now, I go to get back on and the character will crash soon after I get back on.
On two occasions, the characters have been shoved halfway across the map.
For one, my character loaded UNDER the map and crashed (after the first crash)
Then, another character loaded at the portal to the lonely cave from the grounds and when I tried to move I'd float up (that was a fun experience :')
In other words, I just crash. A lot.
And the characters become unusable for.. a day or so? I don't really know the exact time.
