That is what is happening to me atm. Contacted CS and they mentioned that they are aware of this issue and that they are working on resolving it. Asked me a bunch of questions. I suggest you get every single one of your guys to contact their CS too. Let them know how big is the scope of this issue.
The strange part is that there is no issue whenever I'm on WiFi.
What I believe is happening is that they tried to add a patch as a band aid fix for all the previous game crashes mid battle, missing war stars, missing troops....etc.
I believe the patch is meant to not allow us to continue with the game if our network connection is not near perfect.
Each time you login you have to recollect your resources and all the donation troops are gone if you requested just prior to the network connection err rite? They will nullify whatever action you had taken and reload the last saved upload.
