Ok, now seeing a slightly different crash, I've removed all mods other than Krastorio2 and this one, I can add items to the Constructatron's grid fine, but when I try and get it to work, I get a new crash, If I copy something and then paste it into a blank space of the map (outside existing roboport coverage I get this crash after a few seconds.
The mod Constructron-Continued (1.0.7) caused a non-recoverable error.
Please report this error to the mod author.
