Trial of Sekhemas error

Hello,

I was doing a Trial of Sekhemas this morning using one of the unique relics that disappears after you open the trial and as I was progressing from the 3rd floor of the trial to the 4th I received this error "The terrain generator for the client is out of sync with the server. Please create a new instance and try again.". If my relic did disappear after opening the Trial then I assume creating a new instance will mean I lose out on that unique relic which is extremely disappointing.
