Rotating textures

On my server anyone who places a block from the ic mod and then logs out, when they come back on the texture has rotated all to one side. Most of the machines end up looking like basic machine blocks and blocks like the MFE, MFSU, and the transformers, which depend on certain sides of the blocks, are all messed up. I forgot to mention I am running a bukkit server with buildcraft and redpower 2. I applied the fix for item charges changing upon death, however items still lose charge when a player logs out. Any help will be much appreciated.
