Ice & Fire: Marshan Swamp Bug

[tritiy]

Did you fight him?
After talking to Ice elemental I went to him and I had a fight with him. After that , whenever I enter the castle and click on him it states that he is frozen and there is nothing to do.
Unfortunately I have no idea what to do after that since the quest states that I need to remove the obstacle but I have no idea how to do it.

Yes I fought the Paladin, after the last patch though he is now correctly inactive. In order to remove the stone block you need to talk to the alchemist in Marshan Swamp, his house is north of Squelch's castle.
