Posted May 4, 20232 yr Never got this error until now. I need help understanding what's going on? https://pastebin.com/j0xMmwWj https://imgur.com/a/TG5e3T8
May 4, 20232 yr For the "10,000th" time: https://www.google.com/search?q=failed+to+build+unique+mod+list+after+mod+discovery+site:forums.minecraftforge.net You can't have both jei and rei Even typing that error message into google and clicking "I feel lucky" brings up the correct answer. Something very unusual with modern google. 🙂 Boilerplate: If you don't post your logs/debug.log we can't help you. For curseforge you need to enable the forge debug.log in its minecraft settings. You should also post your crash report if you have one. If there is no error in the log file and you don't have a crash report then post the launcher_log.txt from the minecraft folder. Again for curseforge this will be in your curseforge/minecraft/Install Large files should be posted to a file sharing site like https://gist.github.com You should also read the support forum sticky post.
