At around 6:30 in my commander doesnt want to use its disintigrator despite being in range. I presume it has to do with the com shooting other things at the same time?

He was targeting a cerberus so idk why predictive attack would fail to find a solution.

This cerb was on flat ground though.

Known issue. Issue is that dgun is a higher weapon ID and there is no priority aim. So commanders aim their primary during the frame and it overrides the second weapon.

direct orders such as dgun on ground do take priority over passive attacking.. possibly priority targetting (yellow line) is overiding this.. so pressing stop and dgun on ground not a target should work so long as los is not blocked.. targeting actual units can fail if they are moving away from you and predictive aim thinks it will miss.
