I defeated Hammar Frostheart in vestrilund and went to collect the final runestone I needed. However, when I went to get the runestone, it would not let me collect it. No "press x" thing popped up so I tried clicking on the stone. No such luck. I defeated the other enemies that popped up after the battle in case that was why I could not collect the stone. I still could not get it. Please allow me to collect the stone or update my quest log to say I had collected it. I tried the battle again and still could not get it. Please fix this professor(s), or is it just my computer?
Hammar is in Sudrilund, not Vestrilund. You already have that stone. The Vestrilund stone is in Gurz's Cave. It's up an ice bridge that will appear when you do a quest for Saga Windcaller, to collect Ice Diamonds from him.
