Due to Control V not working you have to retype the specific number of troops to train each time, so it is not possible to train efficient.

I made an earlier post on same subject, at that time was the problem, that the field could not be cleared. It was fixed and game was working perfectly before the last update.

Another problem with Control V not working after the last update, is that you have to retype the same message to every player you want to send it to. Which is highly inconvenient.
