[2.0.54] Arty wagon holds trains inactivity condition at 0 for long time

[Amix213]

1. What did you do?
In sandbox, without biters.
Train with 1 arty wagon (full of ammo) and 1 locomotive with "5s of inactivity" condition.

2. What happened?
When the train arrived at the station, its inactivity condition got stuck at 0.
On the screen there is a tiny green bar, and it's like this for ~8s on this empty save and ~60 s in my 250h run. Guns on the wagon do not move.
Removing all inserters does not solve the issue.
Unchecking "Auto targeting" in artillery wagon makes the issue go away.

I think it broke in one of the last updates, was working fine before.

3. What did you expect to happen instead?
Inactivity condition should start counting 5s immediately.
