connection error & resources help

first thing I have lost connection a couple of times now and the last time I could not even release troops to battle so I got 0 stars for my clan there has got to be a way that it detects that I lost connection and cancels the attacks and give me back all the troops and then lets me keep that attack so I can get stars for my clan.

second thing the resources can be hard to get what if you where to set up a market so you can trade your own resources so for example 1000 gold would be like 500 elixir and 2000 gold + 2000 elixir would = 500 dark elixir that I think would help the game a lot
