I'm having the same issue with RTL on my Nexus tablet i.e. Google Play version of RTL. The problem has appeared in the tutorial and also in a side quest in the middle of my existing Kindred Fire campaign. I fear it's going to keep messing with my RTL experience until it's fixed.
The problem only started happening recently so perhaps the most recent update to address issues with accessing the Delve DLC might have introduced this bug...? I can only guess. I played extensively with a friend over the weekend using his iPad and the problem never happened, so it appears to be limited to the Google Play version from what I've seen myself and read here.
