User blog comment:CzrsiNk/Crawmerax bizarre glitch (new 'bunker' on map)/@comment-2125714-20100616210531

Sorry my post was slightly off target there, misread what you said - but that was my first experience of using Oasis/Sofaking's Hub. Perhaps you need to have Sofaking's DLC3 hub in order for this to work - like you say, could be an artefact from Sofaking's hub that doesn't get flushed when you fast travel to Craw?
