Delve. Crash to LogIn screen after loading. Tried to path into Abyssal city

Bug id: 2,252,150,869

Mac OS Steam client.

Attempted to delve into Abyssal city node. The screen changed into the loading one. After that the game was briefly loaded in delve. After that I was suddenly sent to LogIn screen with the following message:

The terrain generator is out of sync with the server. Please create new instance and try again.

New instance creation didn't help.
The same bug occurred four or five more times.

Attempted to circle around Abyssal city node cluster to enter from the other side.
The same bug occurred.

Attempted to reproduce the bug, but with cities of other type.
The only city I found before was Vaal city. I left one node untouched since that time.

The bug did not occur6 while attempting to path into Vaal city node.
