If any player happen to remove a tree in multiplayer games, other players can see the trees disappearing etc even when they have no vision over area under question.
Fog of war is ignored when it comes to tree removal.
Gameplay wise this bug is more important than it seems to be, especially on maps heavily covered with trees, or gamemodes with special rules (like Nuclear War). On Nuclear War it hints the placements of enemy buildings (in the past players used to bulldoser trees off for some extra building space, so their bases don't get removed with a single shot); on maps like The Abyss it may give away potential attacks.
When I choose to stay with americans on 12 mission, the cutscene starts when americans go to russian base, when they reach the river, there is no information about retreat, people are going on the east side of river but american tanks are attacking russians and win, game dosen't give to player control. If you stay longer it will play other dialog lines and even Powell will give support troops.
I have a lot of mods installed and quite often after loading one I'm wondering which one I actually loaded. And because of that I have to go back to mod selection menu and search which is selected. In main menu in bottom-right corner there is shown mod version so you already have it partially done but it would be even better if you would add mod name to it as well.
