Attempting to put any Micro or Mini Machines into an Upscaler causes a crash:

sounds like they're adding stuff in data-final-fixes

Should I leave them a message and notify them, or do you have a fix?

try 1.1.6 and let me know if it works

looks like you're on stable so if you're playing singleplayer just unzip the mod and add the two new lines with (?) to the info.json yourself:

https://github.com/Quezler/glutenfree/commit/9bbc88fcda592d68be3c3ffd08fe0957f3d14515

(and the version to 1.1.5, that way once 2.0.28 becomes stable the game will still try to download 1.1.6)

I have a few friends who play as well, I'll have to distribute this to them, is that okay?

that is fine

It worked, thank you!

allright np, enjoy playing
