Fire and... hey, why are you stuck?!

[Osi_3d]

Hello,
I have an issue in the mission editor: I can’t get a missile artillery unit to move towards its first waypoint. Once the attack is finished, the artillery doesn’t proceed to the first waypoint, even if I add the “go to waypoint” option after “fire at point.”
What’s curious is that this works fine with regular shell artillery.

Anyone else having this issue, or am I doing something wrong?

Have a goog day.
