Wrong location! error in a certain chunk

[flabble]

Whether it be on ultimate, direwolf, or the minecrack mod pack, I get this error in the console. The console keeps getting spammed with red text, here is a few of them:
[INFO] [STDERR] at java.lang.Thread.dumpStack(Unknown Source)
[INFO] [STDERR] at zz.a(Chunk.java:923)
[INFO] [STDERR] at aam.a(AnvilChunkLoader.java:406)
[INFO] [STDERR] at aam.a(AnvilChunkLoader.java:103)
[INFO] [STDERR] at aam.a(AnvilChunkLoader.java:83)
[INFO] [STDERR] at im.f(ChunkProviderServer.java:182)
[INFO] [STDERR] at im.f(ChunkProviderServer.java:118)

And then every once in a while ill get a line in white that says:
Wrong location! ow['Bat'/1625, l='My FTB MAP', x=-1484.43, y=38.10, z=-8356.16]

The coordinates are all different but only differ with very small amounts
