Two strange problems

[DaPorkchop_]

Ok. Tell me if this is in the wrong section, I didn't know where I should put this.

 

I have 2 problems with my custom modpack, both involving servers.  Befone anyone asks, yes both client and server are running forge 1.7.10 - 10.13.4.1614.

 

First problem:

Whenever certain people connect to my modded server, their client immediately crashes. 

Server log= http://pastebin.com/3GjFXX0M

Client crash= http://pastebin.com/XsRtHJSi

Deleting playerdata fixes it, but... yeah. Players like having their items on them, not in the recycle bin.

 

Second problem:

There also seem to be certian places where nobody can go to.  If they go anywhere near these areas they are kicked off the server with the following screen:

The server prints the following message:

None of which help me very much.  This can be fixed by teleporting the player back to spawn via NBTExplorer or deleting playerdata.

 

Any ideas on how I can fix either of these issues? If the issue(s) are from a mod and not forge, sorry, none of the error messages say very much.

Thanks!

Nevermind, I fixed it by removing BoP and when that didn't help, Clonecraft as well.  Didn't really need it anyway.
