Hi, Marcus,
I emailed you from my Thunderbolt along with the log about an odd issue. It seems to have been a one time thing but maybe the logs will reveal more. When I updated from 3.0.15 to 3.0.16 I tried a Prune and got an error that said "it appears Podtrapper started in an unusual manner. Pruning is not safe at this time". Or words to that effect. A reboot of the device and a download of a few podcasts seems to have set all back to normal. Ran a Prune after the downloads finished. Got no error message and successfully pruned one file.
Just thought I'd throw it out here in case anyone else sees this error.
