"The given sprite rectangle (64x64) is outside the actual sprite size left (32x32), Sorite name: OmageDrill/graphics/icons/omega-drill.png.
If this is being used as an icon you may need to define the icon_size property."

I tested it with a lot of other mods, though, so maybe they're interacting or you didn't test with most recent factorio (insisting on sprite size is a recent change).

Do you have research queue? In that case, try to disable that. I have seen it cause A LOT of issues and false positives and if it hasn't been updated, that might still be the case.
