When starting a new map, I got the following error:

The mod Space Spidertron (0.1.4) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event space-spidertron::on_spider_command_completed (ID 170)
space-spidertron/control.lua:86: attempt to index field 'spiders' (a nil value)
stack traceback:

Thanks for the report!

Oof, that's an embarresing error. It should work if you start the new map without this mod, and then add it afterwards. Will do a real fix in the day or so.

Should be fixed in the latest release. Thanks!

Fixed. Could start a new game with the mod directly enabled.
