I was going to start a thread about this as a bug as well. This is happening to me repeatedly as well. It shows I have above 90% chance to hit, and then miss 2 or 3 times in a row with that percentage chance to hit. If there is something that is affecting the chance to hit that actually reduces the chance to hit to a lower number, it should be reported in the text that is saying "94%" or whatever. If dodge chance is affecting it, for example, that should be reflected. Otherwise, it just seems like a complete bug to me.
Besides, how does a level 4 appropriate enemy have enough dodge chance to reduce a 94% chance to hit to a value that reliably misses 3 times in a row? Something is definitely a bug here. I also notice it seems to happen more often with ranged attacks, but NOT at a distance, but instead up close.
