Earlier:I seem to have issues with the 'Q' button:
1: Flying in a void Mystcraft world looking for libraries
2: Having an Efficiency V, Sharpness V, Looting III, Fortune III, Soulbury Draconic Staff of Power in hand.
3: Ender pouch on slot 1
4: Let's free up inventory space, send home the pages gathered (still flying in void)
5: Press Q instead of 1
6: Profit
And then...
1: Log back on after raging
2: Start exploring Thaumcraft
3: Have the fully enchanted Draconic bow on slot 4
4: Have the shards to be thrown to crucible on slots 5-6-7
5: While in the middle of wildly throwing stuff in press 4 accidentally
6: Watch the bow turned into lots of different types of essentia.
7: Get drowned in flux
8: Profit
Grandmaster+++ Adamantine Scythe, loss to lava.
I was in the nether, and didn't have death waypoints on.
