Laberyth of the Ancients bug?

The other day I was pulled in there via alliance raid, and when I went to turn left into the starting area with everybody else, there was this black purple forcefield.

All three passages from the starting area, completely blocked off (and no, the bottom area wasn't accessible yet either)

I can slap some pictures onto IMGR if needed, but has anybody else in here ever encountered that?

I encountered that once recently as well. Everyone else ran straight through it, but I was blocked off.

I can't remember if it opened eventually or if I had to wait for the "warp to sealed area" prompt. More likely the latter, though.

I've got screenshots and maybe video saved, though I have limited access to my PS4 at the moment.

same happened to me
pretty odd
