The bats invasion killed all my pigs and a few wolves - not impressed.
I didn't have this issue during testing.

The first time I got it i was near my pig pen. I have a roof on it because i knew once i beat the swamp i could be invaded by the drakes. I thought it was pretty secure but there was this tiny gap above the door, enough to fit a 1x2 wood panel and sure enough 2 bats got in there and killed 4 of my pigs. I redesigned.
