When I click terminal on lvl 4 after mining all necessary core chunks I am getting this message and save game crashed (+ I am playing with editor extensions and with enemies turned off, idk but maybe this is a case of this error?)

The mod Planet Erimos Prime (0.2.0) caused a non-recoverable error.
Please report this error to the mod author.
