This is a really old and well known problem, I'm talking about the issue when trying to play "arena multiplayer", usually the first match loads without problems, but when going to the second match (when changing from titan to warrior) the screen blacks out and after 10-20 seconds it shows the CONNECTION LOST message.
I want to revive this discussion, because with all these news about IB2 and clash mobs and all that stuff it looks like that Epic is gonna leave this issue pass away... I think that they should fix it. Personally I still play IB1 (I stopped playing IB2 when I lost my saved game because of the bug...), and honestly I like the versus style fight more than the cooperative style they're doing with that "clash mobs", Epic shouldn't just look away from problems... because a lot of people are still playing IB1 online and we want a FUNCTIONAL game, we paid for it. It's really so hard to fix such a stupid issue? It's a shame.
Epic shouldn't give such a bad image with things like these.
