Terrain Generator Out of Sync with Server - Trial of Sekhemas

Bug report #: 1,001,229,293

Trying to open a 3 floor Sekhema Trial area level 61 with an Infernalist. Upon trying to load the very first room I get kicked to login with the prompt:

"Terrain Generator is out of sync with Server. Please load a new instance and try again"

I can confirm the error is not related to Hellhound, skeletons being summoned. I cannot confirm if a relic is doing it but it seems all relic metrics have been loaded properly as I can at least access the map.

Possibly related, this is an old barrya I got on like the first weekend of EA.

Additional: Threw that barrya out and tried another. That one worked fine.
