Hi, I like your mod I have used it a lot and that's why I'm just dropping by to let you know.
Mod does not work with all Pymod and K2 mods.

Regarding Pymods; yes, it is marked as Incompatible for a reason (there's some kind of conflict between stdlib's data:copy functions and pyanodon's post-processing, both of which are required for either mod to function). Attempts were made at resolving the issue, but they didn't seem interested in helping track down the source of the problem.

As for Krastorio 2, it should be compatible, last time I tested (both the vanilla and Spaced Out versions)

This is the error report with K2.
Maybe you are using a modified version, but it is generating an error for me.

I don't understand the problem with PyMod, is it that they use the same function?
Factorio 2.0 has util:
require("util") --- Library
util.copy() --- DeepCopy

OH, sorry, I was working on a different mod earlier and didn't notice which mod this was posted under. Yeah, I don't remember if I ever went back to make Krastorio 2 compatible, I'll have to look into that.

As for the issue with pymods, yeah, I didn't understand it either. But whatever the problem is, whenever any of my mods uses data:copy, it causes an error on load with a very unhelpful error message, or worse (I've had infinite loads before, requiring force-close via Task Manager, very bad stuff)
