When Clicking on the Item Network Terminal after connecting the Cras Site Space ship to it the game gives me the following error:
The mod Items Network [BETA] (1.3.1) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event items-network::on_gui_opened (ID 102)

Which seems to mostly come from not checking if something is a valid sprite path before trying to use it.
