Not sure if this is a bug or meant to be this way. I paid for a practice reset and I assumed that, like other practice resets, it would be good for 5 deaths. My next death also reset my practices so it appears that there is no corollation between buying a practice reset and getting one naturally. It seems like I wasted several hundred crowns and would have waited until my next death vs paying for the reset.
Again this doesn't seem like a bug but maybe a feature that can be looked at.
