Hi Alex, why do you removed them? I mean it is only a little change necessary to make them work correctly.

Regards,
Lukas

    Hey guys,

    I ran into following error message "Bad range: 4294967296"
    That affect rule 28519 and 28514. The problem here is following
    part:

        byte_test:4,>,4294967296,18,relative,little;

    Under 32bit the maximum Int is 2^32-1 but in the rule you forgot
    to subtract 1.
    I checked also the documentation and the maximum for your
    byte_test is 4294967295.

    Could you double check that?

    Cheers,
    Lukas
