1.0.3: crashing in creative inventory

[baddestbassist]

Version:
1.0.3

What is the bug:
game crashes while in creative menu and searching from page 5 to page 6. never displays page 6, just freezes and crashes a couple seconds later. crash report doesn't really show me much, but maybe somebody smarter than me can figure it out. only does this on server. doesn't do it on single player.

Mod & Version:

Can it be repeated:
repeats on multiple people on server only. single player works fine

Known Fix:

 

[GMJ]

apparently, it crashed because of a item that it tries to render but it fails, because the item is ~null~ (as shown here :
-- Item being rendered --
Details:
Item Type: null
Item Aux: ~~ERROR~~ NullPointerException: null
Item NBT: null
Item Foil: ~~ERROR~~ NullPointerException: null )

maybe some kind of incompatibility between mod and server, if you Modified the pack in any way, undo it, maybe that will do the trick

EDIT: or check if the mods and versions on the local pack matches with those on the server, could also be that depending on the mod and the update made
