I m saying
I moved your pot file into that wp language folder
and your theme and system doesnt see it
when its basel/language folder all translation works perfectly
but it doesnt work in language/themes folder
And for people want to move to that folder you could write some instructions (without Loco)
for example I moved it but it seems its not a just simple move file from one folder to another folder process, it needs one line in it to path.
Actually I m helping you out more than you help me out to show you what most people want from themes.
