How do you know if you have buffed someone?

Is there any way of finding if you have buffed someones buildings, for instance, if they ask you to buff 10 coking plants, but they have 12, then they claim you missed 2, and that 2 were already buffed by another player. ((Hope that makes sense!))

Think it may tell you in your news tab,when you buff one,you may need to count though :(

Thanks, is there any sign of anyway of checking this. Not sure if it is a problem, but there is a lot of basket swapping, and whilst I have never had a problem before now, looking at it objectively, there is always the possibility with so many baskets being swapped, mistakes could be made?
