An issue appears after downloading Factorio+, which goes as following:
Failed to load mods: The given sprite rectangle (left_top=0x0, right_bottom=120x120) is outside the actual sprite size (left_top=0x0, right_bottom=120x64).
If this is being used as an icon you may need to define the icon_size property.
See the log file for more information.: factorioplus/graphics/icons/personal-roboport-mk1-equipment.png
This issue does not happen without Factorio+, however Factorio also suggests disabling PlanetsLib, Bob's Equipment, AAI Programmable Vehicles, and the planets Igrys and Paracelsin.
