"failed to save beast"

Bought 10x vivid vultures for 76d, went to menagerie, right clicked the beasts, after a little while i got message "failed to save beast" x10 and now the beasts are gone, not in my inventory, stash, or beastiary. 76d, gone.

I enjoyed the game but I don't think I'll be coming back after this.. That was like 1month of playing/farming for me - and now just vanished when I tried to do the thing I saved for a month :(

Very old bug sadly. There is a chance that if you relog the beasts will be in the beastiary when you log back in. Otherwise they will be gone and GGG has a no refund policy for lost items due to a bug.

Tried relogging multiple times.. Nothing. For many this might be "just 76d" but for me with all the working - not having time to play like I used to, it was over a month of farming.

I really did enjoy the game but I really don't feel like opening it anymore.
