REPRO MISSION
Sometimes it can be really hard to get the right conditions for the successful repro of the issue. That's where repro missions come in handy the most. Simple repro mission with as few units as possible, preferrably in VR (if issue is not related to specific map) is much better then 20 additional repro steps.
