Lag in one spot, not in another

[conjohn234]

So I'm playing FTB monster and I had just installed some floodlights into my lab, I return to the village that my bed and current home is in and all of the sudden i completely lose frames. 0-2 per second, i try walking back a few steps and everything is working fine. It's sort of like there is a wall at x:304 all across my world and as soon as i cross it, (from x:303 to x:305) I lose frames. Any ideas why this is happening? I would really like to be able to play this world again and get back to my house. I have a few ideas that I'm going to try but I'd like to here if anyone else has some advice. Thanks

Rotary craft floodlight? Make sure it's underground. When above ground, it can BUTCHER your FPS. If you must use it above ground, make sure there is a wall for the light to stop on. Make it tall and wide, and not glass. Not sure if that'll work though.

Try v17b of RC. It improves floodlight performance.
