Hi rimbas,
I'm seeing two warnings with your mod:
Warning! Sprite at {0,0; 64x64} from mining-patch-planner/graphics/no-entity-zero.png is defined with 3 mipmap levels, but level 2 is expected to be at {96,0; 16x16} which is out of bounds of the source image.
Warning! Sprite at {0,0; 64x64} from mining-patch-planner/graphics/omit_landfill.png is defined with 3 mipmap levels, but level 1 is expected to be at {64,0; 32x32} which is out of bounds of the source image.
This is fixed by setting the mipmap level to "2" for no-entity-zero.png and to "1" for omit_landfill.png. Would you mind changing those in your version of the mod? Thanks! :)
