Thanks, Norb.Thanks, all the logs I've seen lately are packets that just are not arriving for what ever reason. The low level network code I use should not allow this, but it's happening somehow. We just played over an hour, 6 of us, using brig couriers and it ran great. We did what ever we could to mess it up, but it ran solid. Maybe we just didn't play long enough or maybe some redundancy that I've recently put in is working. Look for another beta patch this week. We'll keep trying until we figure it out.
For hour-plus, players vs players games, played without mods, we are getting about a 50 / 50 success rate. My feeling is that messages sent via the courier window are more of an issue than couriers sent as a result of pointing and clicking on the toolbar (and couriers being set at brigade). Some games we seem to send quite a lot of the former (normally messages to other players) and sometimes each general is so involved in their own bit of the battle that communication between players is quite sporadic. To test the game, we should probably bombard other players with courier messages.
Thanks again for all the efforts on this. Playing MP with couriers and HITS is such an experience it will be great when it works reliably for everyone.
