This wasn't prevalent at the beginning of the game, but around 2-3 hours into a colony build as Casual.
I've noticed at some point, all objects/bots/AI/animals are now invulnerable.
E.g; when hunting, animals don't take hits from any weapons regardless of choice. I'm unable to mine any mountains/caves, I can see the colonist attempting to mine but the hit points of the object are not depleting.
However I have noticed I can continue to harvest plants (fruit, potatoes), trees without an issue. It seems to be animals, limestone etc specifically.
Expected Results - Animals, limestone etc should be able to be damaged/killed/mined.
Actual Results - Colonist continues to attempt to hunt and mine but the object isn't changed. Colonist continues to try and hunt/mine even when starving.
