The order and its running script#

Inspect the actual order handle and ship queue. A script end or interruption event does not always mean the order was removed. In X4 9.00 research, event_object_order_cancelled occurred when a priority order interrupted behavior, while the previous handle remained in the queue as ready.

Verify cancellation#

Confirm that the correct ship exists, the intended order is cancelled and the handle is truly absent afterward. One event is insufficient. The opposite race is also possible: a handle may disappear before a delayed event. Define completion conditions for the specific operation.

Priority and movement#

immediate and priority on create_order mean different things. Read the real queue order after changing priority; a local $Priority variable proves nothing about AI behavior. For movement, also check final coordinates. Script completion alone does not prove arrival.

Regression#

Test a normal order, several queued actions, priority interruption, cancellation and save loading. Do not generalize one MoveWait result to every AI script. See game effect verification and MD persistence.
