As the title says, Thorium fuel cells look about 1/4 of the size of Uranium ones on transport belts (but their filter/recipe icons are the same size). I haven't produced Plutonium yet so I don't know if Plutonium or MOX fuel cells are affected as well. I suspect it has to do with changes in parsing icons in 2.0 but I don't know enough to pinpoint exactly what has gone wrong.
I just produced a piece of raw Plutonium and it also looks too small on a transport belt (but not in inventories). But oddly, the raw Thorium (not the fuel cells, just the brown lumps of it) looks just fine on the belts.
I think I kind of accidentally gave away how much my typical nuclear power setup depends on logistics bots given that I never noticed how stuff looks on belts!
