(Referencing issue on Railcraft GitHub: Railcraft/Railcraft/issues/452)

As mentioned in that issue, World Anchors function improperly when moved by FL frames. The anchor does keep the area loaded. However, on each move, the anchor gets a new Forge chunkloading ticket, and fails to ever release old ones. Because of this, after enough moves, Railcraft is denied any more Forge tickets and all world anchors stop working until server restart.

Of note, Chickenbones's Chunk Loader supposedly functions correctly (I haven't personally verified this).

Finally, also in that issue, CovertJaguar mentions:

• It's possible Funky Locomotion does "...something exceedingly odd, like recreate the tile entity on move without invalidating the old one..."
• World Anchors worked fine under RedPower frames, so something about how Funky Locomotion does frames must be different.

Not sure which mod is causing this weird behavior, or whether it's a weird interaction. Any resolution to this would be greatly appreciated, as we don't have CB's chunkloaders installed on the server I play on. Thanks!
