So I completed Dragonspyre a long time ago meaning I went through the Forum and the Crystal Grove. Now a long time later I want to go back there to do a few side quests but the gates are locked again and I can't go in! Is this normal or is it some kind of glitch?
A few years ago, there was a weird bug that locked people out of areas they'd previously opened through questing. It was all over the spiral. You might have run into that bug, or else there's something else going on - but either way, Support can get those areas unlocked for you again.
