Hi rinigus, I have tested your bugfix release. First I setup an environment to reproduce the problem. For that I used Laufhelden 0.9.8-9 and mapboxgl-qml-1.1.1-10.29.1. Then I put an autosave file of a large workout into the /Laufelden directory and then started the app. Then while loading the autosave the app crashed. Then I just switched to your new release mapboxgl-qml-1.1.2-10.31.1. everything else I left untouched. When I now start the app, it still freezes for about 30 seconds, but then it recoveres and starts working normally. So I can say: bug fixed, good job!
