When I request troops and receive them, my troop request in the chat appears as if nobody has donated. The donated troops can be used normally, but when I'm able to request again my troop request just disappears in the chat and nobody can send me troops. Also, sometimes other members of my alliance request troops and when I try to donate the number of troops donated will increase and then decrease. I don't lose any troops but presumably this is related to the same issue and, even though troops have been donated, the request persists even though it is no longer available.
