Boars randomly stopping?

Hello r/aoe2!

Has anyone noticed that boars will sometimes stop following the luring villager, irrespective of whether or not the villager is within line of sight? When it happens, it usually happens within a second or two into the chase; however, I just had a game in which the boar stopped about a tile away from the Town Center and immediately began walking back (I did not garrison the luring villager).

It's happening in single-player while I'm practicing build orders, so I'd be shocked if it weren't also happening in multiplayer. I've only began noticing after this latest patch.
