It's a problem affecting every monster encounter after you reach a certain point in the game. New to this patch. I've seen it happen with slugs, mirage, worms beneath the desert, and a couple others..
Ah I see, I'll just wait for a hotfix/bug fix then because it honestly makes the game unplayable with that glitch going on. I do hope the developers gets alerted to it quickly or I might send him a message
In case you didn't see, game has been updated. Bug should be fixed now. Make sure you use a save BEFORE the issues though, as I don't think it can retroactively solve them.
