Farm sim 19{animal pens} diabled

Someone else recently was having issues with the Multiplayer component of FS19, though they could connect but kept getting disconnected. Seems to have been an issue on all platforms for some time as you can find STeam posts going back to when it was released

Still not sure about the stables and holding pens for animals though. I see a lot of Bandits hanging around outside at times so haven't bothered with any animals. I'm guessing I have to put fish eggs into the hatchery to start fish farming.

The pens in which you keep the animals must be small. If they can wonder more than, say, 20 blocks within the pen, they will vanish. Also, make sure that there is not a block inside the gate that will provide your animal a stepping stool out of the pen.
If you can get out of the pen without placing or removing any blocks, so can your animals.

Simulator games do that for me. Farm Sim, Sailing Sim and Truck Sim are the big ones for that.

I've managed to herd to 2 sheep into a pen by pushing and hitting them in the direction I wanted them to go.
