Could you contact me to [email protected] and we will try to solve the issue?
I told to my friend that he will contact you if problem persists. Last two rides went without any troubles so it seems that crash is quite rare.
btw. I found one tiny bug. If you adjust some settings and save settings custom map check box is not active anymore. Luckily you don´t have to input address again. That happen at least if you are riding and adjust setting at same time.
