I'm on the latest firmware 1.1.0.73. Come to think of it, we should always include the firmware version when reporting issues...
The bug is very specific, it only manifests after the
first selection of P9 following selection of P10. The cause is probably in the patch data, having nothing to do with the locations as such (perhaps someone could confirm that).
Edit: I have now saved the two patches to two other locations, P6 and P5, and there's the exact same issue with these two copies, so the anomaly is caused by the patch data.
Edit 2: Video attached. Please excuse the bad video/audio quality - I go with ruggedized dumb-phones...
Edit 3: Attempt to reupload a slightly better video gives an error saying it was to large at 1.04MB despite the posting editor saying 4MB is OK, also the posting editor becomes unable to save or preview after that error (something for the webmaster to fix...) .
Edit 4: Video removed now that the issue is verified.
