Title Can't launch the world [Project Ozone 2 : Reloaded] Launcher Type Twitch Desktop App Modpack Project Ozone 2 : Reloaded Modpack version 2.2.9 Have you modified the pack? Yes Link to log file https://pastebin.com/xrygrjD3 Details of the issue I come towards you because I meet a problem with this modpack. When I launch my world, the game crash and I obtain these logs : https://pastebin.com/xrygrjD3 I have add Morpheus and Schematica to the pack, but that didn't put concerns until now. After some searches, its turn out that it's SimpleAchievements who raises problem. I thus tried to update it, even to delete it and all its folders, however nothing can be done. When we delete it and when we launch the world, the game returns simply to the main menu. I have tried to use a backup of my world, but it the same when I use it... I don't understand why. It's appear that it's a known issue, but I didn't manage to find of solution, in spite of all the subjects already opened above. I add you here the logs of the launcher to the starting up of the game : https://pastebin.com/LyNvttW3 To the launch of the world with Simple Achievements : https://pastebin.com/xrygrjD3 And finally without the mod which raises problem : https://pastebin.com/dwgasUDS Thank you for your help, I really need you ! Sorry for mistakes, I'm french and my english isn't at the top ^^'
