´´Dragon Mounts Legacy (dragonmounts) encountered an error during the common_setup event phase´´
That appears when I try to start the game, I used to play in minecraft 1.12.2 with dragon mounts 2. I use minecraft premium edition.
Please help :(

Any chance you can attach a crash log? if you need help, a quick google search should do the trick

I'm going to assume this issue is fixed. If it isn't, try updating your forge version
