In MP game confusion with ally researches happens with every second player. It happens cause of latency. Player see that res. ico don't have heart in res.list & press it. But at the same time another player do the same, so while they research the same thing, they can't really understand it. Common player think "If I don't see heart in time I'm adding this res. to research it, so its. OK."
well long story short: I recommend to add this little "ally heart" to research lab queue, like it show on pic.
I know that there are many way to fix this confusion thing, like "remove res. item while someone researching it" or similar, but my way would be easiest
I would love to see this feature in 2.3.5
P.s. I remember a while ago I suggested to divide Ideas & suggestions forums, for "real" & "unreal" proposals. Seems like nothing happens. Sad
