How To Fix FTBU Chunkloader crash

If you place another chunkloader inside chunkloaded FTBU area, it Will crash.

Until I figure out how to fix this bug, here is what you do if you get this bug:
(For this fix, let's assume that crashing chunk is x54, z111, dimension 0)

java.lang.IllegalArgumentException: Multiple entries with same key: [54, 111]=[net.minecraftforge.common.ForgeChunkManager$Ticket@56212faf] and [0,54,111]=[net.minecraftforge.common.ForgeChunkManager$Ticket@2628cdcc]

Go to your
server/world/LatMod/ClaimedChunks.json
And search for a key that looks something like this

[
  54,
  111,
  1
]

Now, go ahed and remove the 1, so it looks like this:

[
  54,
  111
]

(If its all compressed, look for [54,111,1] and set it to [54,111])
