Hi there, I'm attempting to build support for this mod pack for the FactorioLab production calculator.
Some internal prototype names in this mod pack contain the character ':'. While allowed by the game, this character is not allowed in the Windows file system as part of a file name, which is causing the Factorio dump-icon-sprites command to fail to dump some icons from this mod pack. As an example, one of the problematic names is "ei_solid-fuel:residual-oil".
One of the developers has suggested to just not use that character in mods if you want the sprite dump to work. I'm requesting that the dump command do something at least a little more elegant than the current behavior, but I thought I would at least try to reach out to see if that might be something you would consider.
