I have them set up in my Evolution configuration. But when I play "Normal" mode, they never seem to appear as an upgrade choice. Do I have the world's unluckiest random number generator? Or is there a drop table that got screwed up in a recent release?...

I get lagging spikes (I'm running a toaster, but still) when I use the grenade launcher for digging.

Because it's frustrating to see keys around while descending

Why can I choose my character, loadout and upgrades on Evolution Normal and Weekly, but not on the Daily? (and if that's a feature, maybe a tooltip to explain stuff before we go in?)

I don't really know when I get hurt in the action, maybe some red flash or something?
