Error while running event subterra::on_init()
subterra/scripts/events/initialization.lua:116: attempt to call field 'underground_whitelist' (a table value)
stack traceback:

Thanks for the report. This has been fixed in 0.5.2.

Ty for fixing it. After loading my savegame it seems that the game is freezing but after 5 Minutes or so it is back to normal. Hope that it will be like this from now on.
