Playing the Exotic Industries pack. Getting a crash on either using the Gate building to view the other world or trying to go there specifically. I believe this may be because your character doesnt't actually go to that planet. Maybe a toggle in settings that keeps everything else and shuts off the actual spidertron on start, so you can stop that spawn later on. Error code is as follows.
The mod Start With Spidertron (1.3.3) caused a non-recoverable error. Please report this error to the mod author. Error while running event Protospidertron;;on_nth_tick(7749895)ProtoSpidertron/control.lua:231: bad argument #2 of 2 to 'get_player' (string expected, got nil)
