I’m not sure if this counts as a bug or feature, but it’s definitely annoying.
When you make a tower in HD, villagers pull aggro. It attacks villagers first and buildings only when there aren’t villagers in range. Even if the villagers return, the tower will attack them again.
When you make a tower in DE, buildings pull aggro. It seems to attack the nearest thing in range. If I tell it to attack villagers, they leave, it starts attacking a building and even when the vils return, the tower won’t attack them unless you manually tell it to. When they leave and return, it keeps attacking a building again.
This gives a huge disadvantage to trush strats because you need to micro your towers. Having the vils pull aggro would be so much better for game experience.
