So I'm making a mod pack, and it seems like every time I just get stuck on 7/7 Completing Initialization, Reloading Listeners, Model Manager or this error happens. I researched all I could and I couldn't find anything for my version or any sort of fix at all. https://gist.github.com/Daffehh/68cfb996f25057304d30039b64e0ac1f

So I've been having issues where in random instances, my server just seizes and times everyone out. I think it's because everytime someone joins, they have this message. Attempting connection with missing mods [] at CLIENT. I'm pretty sure they have the same mods...
