I noticed that while running the fractal of the mists that dusguises your team into charrs (having to rush an ascalonian fortress), if you happen to be using the flamethrower and you try to use a skill like grenade barrage (toolbelt), you’ll unequip your kit to switch to your base weapon, I didn’t check closely if it’s random or not (either if you need a toolbelt skill or which skill actually) ’coz the mobs were just spawning non-stop, but it did happen multiple times.
I’m guessing the issue might be animation-related but not sure.
