We need to ignore Guudes tweet. He's a human being that has has the misfortune of admining a FTB server. This is not a fun thing to do and after a while will grate on your god damn nerves soul especially considering the server is an LP server and needs to preform well. He really outta hand off server debugging to more people (as he's started to do now) to take the pressure off himself.
90% of the issue IMO is the chunk loading/unloading that was happening and is still happening to a lesser degree. RP and overkill setups and apparently three chickens flapping in water are the last 10%. Its possible the wireless redstone is doing something to load and unload chunks as well. The limitations of Minecraft itself are really showing though, and until Minecraft is designed FOR MODDING these sort of issues will rear their ugly head over and over. The game needs hardest ceilings that mods have to follow so this crap doesn't happen. You cant expect people like Nebris to know this stuff is going to cause issues, we are all just here to make cool stuff and have fun.[DOUBLEPOST=1368681806][/DOUBLEPOST]
If you watched the video, GB explained that 90% of their lag issues was due to unloading and loading chunks. Keep up.
