Whilst I was going to train I climbed in to the Stronghold of Security and as soon as I stepped in the portal was gone. I thought it was just one of those graphical problems that I always get but that wasn’t the case as I ran my cursor over where the portal would be and got no selection other than ‘walk here’. I also noticed that around me the summoning obelisk was gone and so was the actual exit.
That was the only problem I found in the Stronghold of Security; the other levels and the end of the first level were completely fine (from what I saw).
I couldn’t find the in-Runescape Gold game bug reporter or the online one as it led me in circles so I put it on here.
