I am getting the following error on trying to load the game. Only mods enabled is the Base Mod and Simple Compress. Originally this error appeared when I tried to load all my mods, but I disabled everything except the aforementioned to check for conflicts.

Failed to load mods: Error in assignID: item with name 'compressed-iron' does not exist.

Source: smelt-compressed-iron-ore (recipe)
Mods to be disabled: * SimpleCompress (2.0.6)

I also pinged you on the Factorio Discord and included a snip of the error from the game.

Replied in discord, but i still can't reproduce it so there is nothing i can do.

Hmm, seems checking the box for resetting mod settings cleared whatever was going on. It now loads properly. Last time I had played with the mod enabled had been 1.1.
