Hey mocacinno, thanks for giving c-lightning a shot. The value mismatch is actually important, no one has ever tried to give that many funds to a lightning wallet so far, and indeed you stumbled over a bug when reading back the funds from the DB. It is fixed in a PR and should be merged soon, at which point the true value of the output will show up :-)

As for the disconnection I don't really know. Are you trying to connect to yourself? `connect 9735` seems to suggest that.
