It's happened to me half a dozen times in the past week alone. But I just don't have the time/opportunity to try and replicate it. All I know is that it happens when giving a distant ability order, like laying sandbags three control points away, happens when giving move orders to move into a garrison as above, etc. but also I believe is the same bug as instances of units simply not responding to ability requests, such as ordering a mortar squad to fire somewhere in the distance and the squad queuing up the ability but not turning to face the right direction and thus never actually firing. Seems like all one bug, but I could be wrong.
I guess it is worth asking: this live or dbp? DBP has toyed with squad AI so that could be a factor in that case. If it's live were talking then it is something else.
CoH2 has always been glitchy with pathing at long distances. A lot of commands just break or stop if it requires too much time or distance. It's not something I can replicate often but it's even shown in worldbuilder where the pathing ruler complete bugs out sometimes when calculating long distances, or moving around a lot of object entities, as far as I can tell.
The mortar issue is a different issue than the squad stuff. Mortars that are given barrage or attack commands outside their range when set up can glitch out. I think nebelwerfers in coh1 has this problem too.
And that isn't considered a bug?
If it were it'd be pretty negligible. That mg pictured must have been like 0.0001 meters off from capping that territory. Except for instances of vehicle capping abilities, only infantry entities are consistent in being able to cap.
***edit
Ferwiner is correct in what I meant about the team weapon itself, not the crew.
