doesn't always find match for example 875:6FACFFFF

[paulh69]

On windows 10/11 there seems to be an error in range calculation?

Cyclone -a 128z5d7nN7PkCuX5qoA4Ys6pmxUYnEy86k -r FAC875:6FAC3875
gives
================== FOUND MATCH! ==================

But changing the search range does not find any match?
Cyclone -a 128z5d7nN7PkCuX5qoA4Ys6pmxUYnEy86k -r 6FAC0000:6FAC3875
gives
