I haven't played 1.3, yet, so I didn't notice the penned-animals problem. I won't play for a few in-game years only to test it, sorry. I if someone has a mid-game (maybe 3-5 years into a run) that has penned animals that would normally qualify for walking them or playing with them then please send me the save game.

E.g. on mediafire/.com. Links to Media Fire aren't allowed in here, so if your uploaded file URL is "www/.mediafire/.com/file/abc_def/MyGame.zip/file", then you only need to post the "abc_def" part. (The slash before the dot has to be deleted of course. Otherwise I couldn't have mentioned the URL at all.)

The save game should not use too many mods. Tens of mods are OK, but please not hundreds.
