Issues 20 and 29 on the bug tracker are the same issue, with an important detail that it's both MIKE and KILO that have duplicate server racks that are placed in the exact same position.
To clarify:There are 2 Kilo servers both at the exact same spot, and 2 Mike servers both at the exact same spot, overlapped. Thus causing floppy disks to get stuck since the cooldown for re-entry of one slot does not apply to the duplicate slot.
Weirdly, of the duplicate servers, there seems to be a "primary" server, each. If you place a floppy into one, then go to the console and type "sv.eject" and it fails, then the floppy is in the duplicate. If it succeeds, then the floppy was in the correct "primary" server, and it has now been ejected and re-inserted into the duplicate.
A temporary workaround for struggling with the hashes that I've been doing is placing a red floppy (since they're shit) into the server, and sv.eject-ing it so that it goes into the duplicate server. That way I can drop a good floppy and physically move it to the slot so the correct one grabs it.
Kerfurs get stuck in a pathing loop if either Mike or Kilo are on the list, however.
