I am not sure, but I think the memoryhogger issue still exists. Minecraft now crashes on loading my world, possibly because of the ~300 solar panels I made. It runs out of memory before I can do anything. It also lags terribly whenever I try to place glass fiber cable that will connect to at least 2 other glass fiber cables.(not sure about other cable types) The fact that those cables are linked to my solar grid may have something to do with it. (They are linked through MFSU's)
Edit: Error log when it nearly crashed but managed to recover:
