Bought "The Purple Tear's Page" in the shop.

I'm no longer able to right click the Relic, got to a Rest spot, and I'm able to change it and it works again, but equipping it makes it unable to be clicked again.

I went through a few turns of combat as well and the "Stance" doesn't seem to work either.
Says to choose one and it takes one turn to ready but, nothing ever showed up for me to choose one.
The "Speed3" on it is working.
