Gates in siege randomly open

[Malenthas]

I'm defending a city with tier 3 walls. The gates are not breached (only 20% damaged.) But the gates just randomly open, allowing the enemy units to walk in to my city.

Anyone else have this issue?

I've experienced it in the past as the attacker, where a unit (often a single entity like a lord or monster) somehow ends up walking through a gate then getting trapped on the other side. This is the first time I've experienced an open gate as a defender.

It happens when a defender's unit gets too close to the gate, since the gates will normally open automatically to let the units of whoever controls the gate through.

Yes, keep your guys nearby but hanging back away from the door.

It also can help prevent your single unit from getting blasted while his friends watch from behind since they can't reach anyone over the heads of your unit that opened the door and then got aggroed and walked over to the gateway and now is blocking the entrance with their own hit points.

It happened to me a few times before I determined there are good reasons for the shield icon, and unit placement for a siege defense can be one of those times.

getting the same problem but my people arent that close to the gate below but on top. Below troops are on the boarder of the yellow area box around the gate. surely thats not classes as close?

Bug as old as the game. Never fixed and never will be
