since Dec 22 nightly build for windows x64 the "save playlist to file" function is broken (it is still broken with nightly build from jan 19, 2017
I can load a m3u playlist and edit and rearrange items, but when I try to save the modifications file selection dialog appears then the overwrite warning and then the file is not changed.
Same happens when creating a new playlist. On Save no overwrite question ofc, but the given filename c:\temp\test.m3u is not saved on disk in temp dir.
