OpenMW-Launcher: you can not use an omwaddon when there is already another one in ~/.local/share/openmw
I have (different versions) of an omwaddon (same filename) in ~/.local/share/openmw/data and in ~/gaming/openmw_DF/ When I select the one in ~/gaming/openmw_DF/ that choice is not saved but the addon in ~/.local/share/openmw/data - actually it can not be used as long as the file in ~/.local/share/openmw/data exists.
I am really sure that this behaviour is new and that it worked to select & play a mod - whereever it was located - some months ago.
howto:
copy mod from ~/.local/share/openmw/ to <your_DataFiles_folder> > start launcher and select mod at <your_DataFiles_folder> > close > start launcher > check which mod made it into ~/.config/openmw/openmw.cfg -> it is not the one you selected
