Dear Calvinus,
yesterday, we tested again and the initial bug in the events was gone. We could proceed in the game. Due to CP warplan choices and Diplomacy, Italy joined the CP. We saved the game then on my (Hosts) PC.
It was the CP players turn and he had to activate AH 8th and 9th Army and Italian 1st and 2nd army.
I booked reaction with French 2nd Army, and when the CP was finished with AH and started with Italy, I was able to react and moved/attacked with 2nd Army successfully. Then my turn ended (tooltip - you are not the active player anymore). BUT the CP player could also not activate both its remaining Italian armies (also tooltip - you are not the active player). Then my buddy left the game and the AI took over and was able to activated the 2 armies (which could not be activated before)
Ok we thought, return to the savegame and try again.
Here a larger problem started for us. We could not resume a savegame (we checked that we had the same names and nationalities selected as we did before the save). We tried with the mentioned savegame and with other saved campaign and scenario starts. Each time we find each other in the MP lobby and select start, then me (Host) got into the game and my buddy got a crash just before entering the game (I think end of the scenario initialization screen). I then got the message "Buddy's name" left the game AI takes over and I could continue against the AI. We could not use a single savegame.
Also an error I saw sometimes in Multiplayer (last time in the Tannenberg scenario): My troops move according to order and enter hexes with enemy units but no combat is initialized (both troops stay in the same hex) or the troops move, enter the target hex (empty or with enemy troops) and then are teleported back to their starting positions.
It would be great, if you could look into MP again
Thanks Hanno
