Old behavior: If you did a successful cast, then tried another cast that failed (e.g. "Your cast did not land in fishable water"), your first cast still persisted.
New behavior: the second failed cast will cancel your first cast.
Loot change: Curious Crates now give up to (at least) 5 netherweave cloth or 5 fel iron ore, and (so far) up to 3 Knothide Leather. Haven't seen Knothide Leather Scraps yet.
