Crashing Underworld

[FriesBeforeGuyz]

So, this is going to need a bit of explaining. (Sorry for the mini essay!)

I don't know where to start when it comes to asking for help with this, so I'm gonna take a chance and start here.

My friends and I built a modpack for just us 5. (I think you already know where I'm going with this). We have 120 mods (Client side, libraries, & cores included) and of course, wizardry is one of them. We have a few mods that add other dimensions already, and they've all worked fine.

Queue me going to the Underworld to slaughter all of Unicorn kind for my own purposes. Jump WEEEEEE Crunch -and then I was kicked from the game. This happened once or twice already with the nether, I just needed to rejoin, right? Well...

The dimension would NOT load in. At all. It would plop me into free-falling space for a little bit (thought I wasn't actually falling, and I would get kicked seconds after), and the free-falling thing happened every 1/4 times. Otherwise, it would just disconnect me after a good solid minute/half of a minute. My next thought: Have someone /kill me when I join so I can just respawn in the overworld. Also fixed Nether stuff (NetherEx was a bit much...).

I think you can already guess that it didn't work. Instead, it crashes the entire dedicated server when I join. YAY!

I have countless crashlogs I can send if need be, I just don't want to break the server any more... I know very well it could definetely be a mod conflict, but since it's only the underworld that's crashing me, and the server by extension, I figured I should start here.

Thank you for reading and sorry for the paragraph(s)!
