Sorry, no clue on reproducing this. But I had a screen freeze a couple of minutes into match. Piloting a Stalker 5S, headed to mid-entrance of the cave on the frozen planet map and had an ECM contact in the cave, then went back down ramp towards our base-side entrance. Halfway to the other entrance, screen froze.
This is the first time this has happened to me, and I have been playing for months. So I assume this is new, or I just finally got lucky.
