Skills becoming unusable?

[dragonjek]

I don't know if I'm getting affected by some sort of debuff I'm just not noticing or if this is a real bug/glitch, but partway through a dungeon I'm sometimes finding some of my skills locked off. I'm an Engineer, in case this is class-specific.

Here's a couple screenshots. As you can see, I can't deploy any turrets nor fire off a quackum, nor can I use any shooting skills despite not being in Mechanic Mode. Even if I do enter Mechanic Mode, I still can't use any of the turret skills.

Anyone know what's wrong?

Oh.
Well, that was simple. And embarrassing.
Thanks for clearing that up.
