[1.4.5] Alt Daikara 4 fails to generate

[Stuntofthelitter]

I've been trying to track this down forever but thanks to Sheila I finally have the error responsible.
This only seems to happen to people with "Zone save per level" enabled.
When the player initially tries to zone in it hangs while generating and never finishes. After being force closed they load back in to a black map that errors out nonstop.

This is the error initially generated in the log when it hangs:

Code: Select all
