Hi, I have the same problem with the same numbers, sometimes people can join and sometimes not. Have you found anything that could help us? I see that you've deleted a lot of addons that we also had like Create / Twilight and other mods. Do you use Essentials with your friends? Maybe it's because of that, but I'm not sure. Perhaps we should compare our mods to see which ones are causing this problem? We tried to remove Create, it's working for the moment but let's see if I'll crash again.
Yours sincerely.
