The error is related to how the tool checks if a mapID is present in input file. This works for what was the original method=area option, but for method=counts this means that mapIDs with 0 counts are not merged with other mapIDs to meet the minimum requirement.

Fix is kinda easy, but initial testing is running far too slow so may need to rework logic to avoid some duplication of effort.
