Hi, I am not 100% sure if it really is as I describe it here, but anyway.
I noticed that whenever I try to name my files by an discogs release id starting with [m (e.h. [m54682]) I get an error rmessage:
"Error connecting to server: www.discogs.com
404: Not found"
At first I thought there was really an issue with the connection at that time, but I can try to do another search directy after that and to another id (e.g. [r1057669], same album but with a different entry), and it will work. Searching for [m54682] again will result in 404 again.
So far I am sure my description is correct, but I think this goes for EVERY discogs entry starting with [m.
Please check, thanks!
