Moderate Bosses, Mobs and Drops Only Crashing on Corsair @ HT

I get visual bugs on my Corsair at LHC and sometimes while using Aerial Strike anywhere. GFX fixes it but it happens regularly.

Then i only dc on my Corsair at HT main body, exactly about 1-2mins in. But none of my other characters DC the whole run even if maining it or muling.
