The desync in co-op (Tom Clancy's Ghost Recon: Wildlands)

Good time of day. Playing co-op is faced with the problem of desynchronization. It consists in the fact that I may not see your opponents, which sees partner and Vice versa, or fly to the convoy, and he is missing. Plus, double spawn. For example, driving a van with fuel, if I play he 1, if you play with friends (We are 3 plays), then spawn 2 of the van. Moreover, the note 2, but the resources are only given once. Same with the ! signs. With opponents generally get a tin. I can see how it sits in wait, he was surrounded by 6 militants shot at point blank range into him, and he them does not see and does not receive damage. All computers meet the recommended requirements, played at my house, and have friends, the situation is the same. Providers are different, was going to play for everyone. And sometimes that'll be all right, but then returned. Cheats, mods and so on, no one uses it. It's a shame the Wildlands and Steam and Uplay? nothing helps. I want to note that I have another No. 3, the game purchased on Steam, and the other No. 2 in Uplay, but I don't think that's the case.
