[bug] immortal animal breaks game

[zandadoum]

Hello,

Here is what happened:

- I had 2 colonies, I left one of them when a psychic ship dropped, which I was unprepared to fight.
- After a while, 3 labrador dogs joined that colony. I decided to abandon that colony then. I got the classical popup telling me I left people behind
- small break from the game. when I came back, there was an update
- After a few game month, those same 3 labrador dogs joined my main colony. but as it's a too cold biome for labradors I decided to sacrifice them.

BOOM! glitch! 3 tamers stand infinitely at those labradors, killing them... but they would keep healing themselves.
I tried attacking them instead of slaughter and this was the result: https://imgur.com/a/tMK7PUW

maybe it was the game update from today that broke something, because i tried some chickens and i can't butcher them either...

the biggest problem is that the game runs at 0,000001% speed now because of this. it renders my current colony unplayable. FPS went down to 2 (was 144 before) but CPU usage is still the same.
