I went through your server log which is quite unreadable with all the debug and trace information. You should now turn these off, as they might slow down your server and cause further refresh/display errors.

Apart from the Mine and Blade: Battlegear2 mod, which is reported to cause problem, I was surprised by the lines such as "Fixed block id mismatch lotr:tile.lotr:blueDwarvenCraftingTable: 486 (init) -> 485 (map).", which could indicate that you are using maps from a world which has a different set of IDs for blocks and items, than the one you imported them to.

Wading through the 211 such lines, I saw 1 coming from the Battlegear mod: "[01:43:48] [Server thread/DEBUG] [FML/]: Fixed block id mismatch battlegear2:flagpole: 165 (init) -> 477 (map).", which could explain the value offset seen in the 210 lines coming from the LOTR mod.

Have you copied the world/level.dat file from your original world, because this is where the Blocks/Items Names/local IDs pairs are stored? Just copying the .mca region files is not enough, when you use several mod adding blocks & items.
