I really appreciate that someone has updated the mod, so thank you, and here is a bug report. Whenever the nanobots are trying to insert something they fail, an error spams the chat, and I think they stop working for all players until this is fixed (by putting the stuff in yourself). This happens no matter what you want to insert - fuel into a ghost train, modules into a machines from a blueprint, whatever. Just something I wanted to mention since no-one else has.

I was just about to make a bug report for this. I have a train in a blueprint with coal as fuel but it errors with whatever its trying to do. I tried to look at the code but did not get far. Here is a quick video for you: https://gyazo.com/c4fe28e4d9e4229bb1e1016bbfdd98b8

Error messages:
_Nanobots2__/scripts/nanobots.lua:337: attempt to compare number with table
_Nanobots2__/scripts/nanobots.lua:64: attempt to index local 'prototype' (a nil value)

Another example of Arcanical's error:

Trying to insert modules from a blueprint when I don't have (and hadn;t researched) the modules (quality in this case):

Nanobots2/scripts/nanobots.lua:64: attempt to index local 'prototype' (a nil value)

Spams continually until I removed the blueprinted inserted mod.
