Problem Minecrack Server item mismatch

[Chthon]

I've added mystcraft to a Minecrack Server (v6), and also to a client with the same version. The same mod pack was added to both. When trying to log into the server it reports an item mismatch between all the mystcraft items.

2012-12-30 05:57:39 [FINE] [ForgeModLoader] The difference set is not equal: only on left={8956=Item 8956, Type xcompwiz.mystcraft.ItemAgebook, owned by Mystcraft, ordinal 0, name null, claimedModId null, 8957=Item 8957, Type xcompwiz.mystcraft.ItemLinkbook, owned by Mystcraft, ordinal 0, name null, claimedModId null, 8958=Item 8958, Type xcompwiz.mystcraft.ItemNotebook, owned by Mystcraft, ordinal 0, name null, claimedModId null, 8959=Item 8959, Type xcompwiz.mystcraft.ItemWritingDesk, owned by Mystcraft, ordinal 0, name null, claimedModId null}: only on right={1288=Item 1288, Type xcompwiz.mystcraft.ItemNotebook, owned by Mystcraft, ordinal 0, name null, claimedModId null, 1289=Item 1289, Type xcompwiz.mystcraft.ItemWritingDesk, owned by Mystcraft, ordinal 0, name null, claimedModId null, 1286=Item 1286, Type xcompwiz.mystcraft.ItemAgebook, owned by Mystcraft, ordinal 0, name null, claimedModId null, 1287=Item 1287, Type xcompwiz.mystcraft.ItemLinkbook, owned by Mystcraft, ordinal 0, name null, claimedModId null}

It appears the FML used to load the item sets is not resolving the items to the same item ID for some reason.
8956 vs 1286 for agebook.
8957 vs. 1287 for linkbook.
8958 vs. 1288 for notebook.
8959 vs. 1289 for writing desk.

Considering all the other mods are identical this should not be happening.

Note: This did not happen in v4, however using the items always resulted in a server crash. The items though did match up properly.

Anyone have any clue how to solve this, or if this is a known issue?
