I finally found the "mirror" of a bug to an older MOLD bug, which prevented sending objects unharmed (e.g. properly MOLD'ed) from the server to the client. The mirror of that bug would not let objects go through from the client to the server, but that works now by changing the MOLD to MOLD/ALL in COMPOSE-MSG on both server and client.

CHECK-MSG in both the client and the server part of Rugby were broken and did not calculate the checksum of the message according to how the checksum is built in COMPOSE-MSG. This has also been fixed.

You can get the latest rugby.r here.

To compare, the older version without this fix is here.
