I am running MV Nether-Portals, Inventories, Portals, and Core, all updated to the Dev Build 2.5.

We have CraftBukkit Beta 1.4.5 B2488.

Whenever I go through a Nether Portal between the Overworld and the Nether, Minecraft crashes. When I connect to the server after the crash, I am in the Nether. It works fine going from Nether to Overworld, but not Overworld to Nether. None of my other members experience this problem.

EDIT: I have pinpointed the source of the problem to be ModLoader. Is there any way you can fix this in a later release?

EDIT 2: Multiple re-installs and reloads later, it works. No clue what made it work.
