Units on walls and some siege engines don't auto-attack

[serveurix]

Units on walls don't attack automatically ennemy units in their line of sight. Same problem for assembled roman scorpio, egyptian polybolos and oxybeles (I haven't checked them all but roman ballistas for example don't have this problem).

If you ask them manually to attack a unit, then they will attack every enemy unit in their line of sight until there is no enemy unit in their line of sight anymore. At the next wave you need to repeat the process. If they are attacked they will react too, as if they were asked manually.

My guess is that the siege engine in its default aggressive stance tries to chase after an enemy unit that got away, but it has a movement speed of 0.001 or something and appears to be doing nothing. Can you reproduce the problem when the siege engine is set to "stand ground" mode?

EDIT: it seems to me that the problem occasionally happens even when the bolt shooter/ballista is on stand ground stance, especially when there are many units on the map.

Backlogging due to lack of progress

Looks fixed in a22 (I've just tried putting units on walls on Miletus). Can anyone confirm ?

Can anyone confirm ?

I can confirm it isn't

Using the same vision range as the attack one (currently it's really bigger (also in many place there is a confusion between los range and attack range)) could be a workaround (not what I recommend).

The remaining part of that ticket (about packed units) should be fixed by r21630.
