Revision A is now live which fixes the softlock on the equip scene. An extra function I'd added in for the class scene was also happening on the equip scene, causing the command window to be deactivated.
In the process of fixing this, I also noticed that the optimize command in the equip scene doesn't seem to properly detect monkeygripping weapons, preferring to equip no weapon in the offhand, and a one-handed offhand weapon over a two-handed weapon with higher attack. I guess I'll have to fix that too while I'm at it.
