Trial of the Sekhemas Floor 4 Test of Time Desynch

Title sums it up.

Context: On entering Floor 4 of Trial of the Sekhemas "Test of Time" for the first time, I clicked the narration object, listened to maybe 3 seconds on started off. Within 5 seconds of walking I crashed into login screen.

The error message said something to the effect of "the terrain engine for the client is desynched with the server, please try opening another instance".

I've tried going back in 4 times, each time the gear animation freezes within 5 seconds and I crash back to login.

Halp

Same here.
