Looks like bug has been reintroduce? With waypoints (and TTS on Waypoint name)
If after passing a waypoint there is only 1 waypoint close Oruxmaps gets it correct. However if there are several close it will say nothing for the closer waypoints and then say the name of what was the closest waypoint at the furthest one of that group.
Ie if there was waypoints 1,2 and 3 it would say nothing for 1 or 2 but at 3 would say 1.
