Seperator unmatched.

[Konvict]

This is not about the 2nd : it can handle it pretty good. You get "Seperator unmatched" if the : is not at possition 33 of the line. In your example it is, so thats a bit strange, you sure its this hash?

Yes im sure, hmm Ive always got it on salts with two colons, but it has still cracked the forementioned hashalts's.
