Mission can be solved twice when connectivity drops

[habi]

I don't know why, but while solving a mission, there was an error connecting to the server.
Nonetheless it seemed to me that I twice got some Koins.
Maybe you should check the connectivity before informing the user about the Koins he/she got.

This short screencast shows the problem: I was able to add the language of 'Zytglogge' twice...

Hi Habi, Thanks for the issue.

Kort development has stalled end of 2017 and there are currently not maintainer nor dev resources available on this project. Around October 2018 there will be some shiny activities in order to resurrect this nice game experience. Pull requests are welcome.
