PSA: Pack Animals can't go over Barricades

[magicjani]

If anyone is having problems with traders showing up without items, no questions marks above the trader's head or their pack animals leaving the map...

Remove the barricades around your base or replace them with sandbags, since animals can't go over barricades and inside your base!

I ran into this a while ago, it was super annoying, my donkey was trapped between a wall and a barricade constantly starving. Good to know sandbags don't stop them!
