.. It would be helpful if the Talisman keys did NOT reset dungeon timers if a dungeon still had more than 57-58 minutes on it.

I drop a key.. it opens the Sentinel dungeon.. but I don't need to do anything in the Sentinel dungeon for achievements at the moment (until I get Max S Odin). So I need to open a different Cosmic dungeon.

The S dungeon has around 59:10 minutes left on it since I just opened it.

I drop another key.... It refreshes the timer on the S dungeon.

This would be expected and absolutely fine if the dungeon was open for a while. But since it JUST opened, the timer shouldn't refresh it.

For the record, I think they longest streak I saw was 4 keys.. they all just keep resetting the open dungeon timer from 59 minutes to 60 minutes.
