I've just tested the game, and I was able to replicate the error with the equipment. There's actually no issue with that system; once again, the error lies in the save system. Specifically, when equipping a character and immediately entering combat, the game doesn't save prior to that change. Now that I know what the problem is, I can confirm that there will be a new patch by tomorrow, or even later today if I have the time, to release the fix.
