So I finally managed to tame my first level 9 bear earlier, put him in a closed off pen with a lvl 1 tame bear later and set them to wander to see if they would breed. Logged back in and in the company log it says he (but not she, she's still alive in the pen) has been killed by a wolf. The same thing happened yesterday when I had two chickens on the upper level of a house, also set to wander to breed and logged back in and they were both dead. One was killed by a wolf and one by a rattlesnake. If they're set to wander are they just bugging out of my house/pen and getting killed or what is going on? Me and my crewmate are asleep in the house as well and have not been killed. I also have 2 cows and a third chicken not set to wander and they've all managed to stay alive. The bear was also sticking his head out of the wall so he could have been killed that way, although it does not explain the chickens dying or why the other bear is still alive when she was on aggressive and only level 1.
I've seen the cows bug out of their pen when I accidentally whistled a "follow" command to apparently all the animals and got to see two cows flying over my house out of their pen which was quite ridiculous The chicken stayed stuck inside.
I've turned all of the wandering off in case this is the problem but would like to know if it is that or if I need to build more walls around the house or something to stop it.
