Something really odd happened to me earlier today, accessing the portal on the Negilahn pod age.
The portal appeared at the correct time, that was no issue, and I stepped through it to reach the cave area. However, about a second after reappearing, I suddenly "linked" again without being able to move. I ended up reappearing in the cave for the Eder Delin and Tsogal ages, with both platforms and switches open for activation (and I had yet to make a group attempt with those).
Obviously, I didn't get the stone I wanted, and I won't be able to try to see if the issue persists until another convenient opening time for me (probably within the next couple days). This was just very unexpected and I'm wondering if this has happened to anyone else before.
EDIT - I should also mention I already acquired the other 3 pod age stones a few days earlier with no issue.
