Well.. many facing while playing the connection lost .. not the multiplayer..but the normal missions.. there is no save..then restart the mission again! so is there any way the normal mission saved online and can continue from the saved one..well..
Player progress is saved on the server, the quest that you were doing when being disconnected should still be in your quest log.. But will have to start fresh, from the beginning ..
I really think an feuture that saves map for restoring would be in place, both for single as well as multiplayer.
Other AoE-games and similar games has it - it should be solvable - and it would be a great feuture for ppl like myself that on the moment is on a wireless internet and drops rather often.
Also in multiplayer the timer that it takes to kick a player out that has problem is far to short and should as in AoE2 be possible to choose to stay and wait how long you like. I drop from time to time and I've noticed that if I disconnect my wireless and connect again I can make it back before the kick - though it's stupid it happens so fast that you drops even you shouldn't need to.
