A friend of mine and I have been trying to get into a multi-player game with one another with very little success, it started off with neither one of us being able to even connect in any form to each others servers, the game just saying they couldn't be found, but we've progressed by a minuscule amount, with it now proclaiming we're on different versions, we're both on 1.03b, but the checksums are always different, he's KUMH or a variant thereof (LUMH after resigning, back to KUMH after relaunching) and mine is YUSG (XUSG on resign, back to YUSG after relaunching), we've both tried removing all local files from both our Steam folders and Documents, but they always end up being KUMH/YUSG, which seems to be the only difference between our games thus what I've pinned our inability to connect to one another on.
Is there some way for us to ensure our checksums end up being identical?
