Whenever I try to load my modpack, it gives me this error: https://imgur.com/evoLfuS
I have the latest versions of every mod installed, and have disabled them for now. Do you think you could look into it?

Also, since several mods don't support this one; perhaps you could make unrecognized tiles render as the default colours or something?

I would disable Factorio Extended Logistics - it looks like you're not the only one it's crashing for. Useful Map Colors does not affect other mods failing (all it's doing is changing one of two variables, map_color or friendly_map_color), and it can't prevent other mods from having bugs.

Things already have 4 chances to get a color - first from config.lua. Failing that, UMC tries to color them like vanilla items, by category. Failing that, they'll appear as whatever their mod told them to, and failing THAT, they'll be Factorio default colors.
