All difficulties created with osu!trainer open/import only to Lazer

[RadialGH]

I started running into this problem a couple days ago, any way I can get it so that the custom difficulties I generate can open back up in Stable? Since there is no way to access the diffs in the Lazer directory I have no way of importing them into Stable since there are no beatmap files to import

a (maybe temporary?) fix that everyone can do that works is adjusting the file association within your windows settings

Open the windows settings app and type this in and click the option below

Scroll down (a lot) until you find these four osu file types

Manually reset them from Lazer to Stable (you can tell which is which by looking at the new vs old logos)
