Can anyone tell me if it is possible to get to the Frozen Lake (trying to reach a forgotten Zeke Beetle) after the quest has been finished. It appears to me that all the doors etc. to reach it are closed and need a lever pulled or a lock unlocked. It is the only beetle that I need to reach and I am stuck. If I need to repeat the quest(s), can anyone tell me name of the quest(s) that will give me access? Thanks for any help.
