Pufts of all types repeatedly become stuck expelling waste. They they do not move and cannot be interacted with without reloading the game. When I reload the game they reset and start eating again so whatever they had eaten previously is lost. I have mostly noticed this with wild pufts but that is likely to be biased as I rarely ranch them (so far). I have seen this issue reported else where but with no update for over a year so I don't know if it had been considered fixed?
Thanks in advance for anything you can do.
Have some pufts. Leave them alone to consume the approapriate gases for a while. Check on them periodically. Notice that one or more has stopped moving and is stuck expelling waste.
