Bug or strange and unexpected behaviour in routing occured driving home from work today. In the.125 beta I added home as my finish, selected a different route than the fastest. Then added a stop in another direction than my general direction home, to pick up family. Once again selected "Routes" to get another route than the first selected. My drive home is about 30 minutes and with the extra stop at least another 20 minutes or so. ETA was displayed as 1 min to stop, which I later realised hadn't been selected but ignored while selecting the other route. Stopped at a bus stop and reentered the routing again doing it in exactly the same way. Same problem occured again. Then I inserted the stop without selecting an alternative route. Everything worked as expected.
I think that when selecting to find an alternative route when navigating with a stop Waze doesn't understand that I want an alternative route to my stop but instead checks for routes to my final destination. The navigation was directing me home instead of via the other place I was going. Strange though with the ETA 1 min.
Will try this frequently in betas to come.
Edit: This was on a Samsung Galaxy note running Android 4.0.4.
