3.) I've seen that happen. It's pretty rare, but it happens. My character has to be right at the edge of the ledge for it to happen. Enemies will rarely stand right on the edge, so it's hard to reproduce in single player. Could probably reproduce it in Arena mode pretty easily, though, with another person helping test.
4.) I've only seen this problem with characters under the influence of the Black Rose potion, so that's probably related to #2.
5.) That's not how you use the word "triggers". Don't pretend like you have PTSD about quest logs. Don't learn vocabulary from Tumblr. That said, the ability to separate out completed quests is a frequently-requested feature.
6.) There does need to be some indication of why those checks are occurring, or some other handling of it. At least the ring tells you that you're cursed when you put it on. It does seem a bit silly to see a notification repeatedly about the curse being deflected due to magic armor. It should just have a debuff icon representing the curse on the character, but the effect remains non-verbose until it can apply the actual debuff (when your magic armor is depleted), at which time it tells you what's being applied and where it's coming from.
