Stuck on level generation: "Level unconnected"

[Noel]

My game seems to be stuck generating the second level of a farportal. The progress bar is still moving, but the log is now showing only in-game chat lines and server latency lines.

The log shows that it tried three times to generate the level, and failed each time with the "Level unconnected" method:

Code: Select all

...generate NPCs and objects...
Level unconnected, no way from entrance to exit	42	39	to	31	34
...generate NPCs and objects...
Level unconnected, no way from entrance to exit	28	32	to	21	52
...generate NPCs and objects...
Level unconnected, no way from entrance to exit	28	32	to	21	52

FWIW, the first level of the farportal was in three separate parts, and needed some digging to explore, but both stairs were in the same part.

When I killed the t-engine process, restarted, and reloaded the save file, the level generated in one try.
