Except if you read the posts you would have read I solo the bosses and only skill I used was riposte to check. For some reason it's doing it a lot after the update idk why. I noticed the numbers were missing because I was obviously watching them lol.+1 this is more than likly your problem or it could also be the boss useing skills when you use riposteSome bosses are too big to see hits or there are too many atks to list and some get skipped.
The second is a big problem for me. Me and a ranger killed something today and it skips over half our skill hits.
I still think there is a bug because I've carefully watched and either riposte was missing or resisted (without it showing up in plain text). And yes for the xth time it was while I was being auto'd. For some reason this only seems to happen on bosses and not regular mobs that I have seen.
