In last level of the crypt I have encountered such bug: some elite archer has fire an arrow in my character and I changed places with my mucus ooze. But in result I had two copy of my character, staying on near tiles. The bad thing is that Melinda is following my inactive copy, so I can not rescue her. All damage done to one of copies also done to other: they are literally the same person.

With best regards, Ilia.
