Game crashes with empty pathgrid

Getting a reliable crash in a specific cell with 0.47 RC7.

Since I can't reproduce with any single save, the best I can do is give these instructions:

1. Install this mod https://www.nexusmods.com/morrowind/mods/50260 and coc Hashur
2. Run around the main open area and hope for a crash
