Trial of The Sekhemas

Hi!
Decided to pass the test with a unique relic the price of which is 2 div - after I passed the first floor I disconnected from the game with the error:

“The terrain generator for the client os out if sync with the server. Please creater a new instance and try again.

I am very offended and lose the desire to play when such an error deprives me of passing the test, especially with such an expensive relic that I could sell!

Help me solve the issue, thank you!
