the help you were offered is a normal way of finding an issue with mods when its not obvious which mod is causing the issue, maybe try doing whats suggested rather than just giving attitude to the person trying to help, no one here has to give help, and giving attitude to those that do help will just put them off helping you further
Here is the thing, I wouldn't be here if I didn't try that, it is common knowledge to try that first
Is it anything to do with world gen from a mod you have possibly like an unfinished mob crashing the game, too many mobs spawning or other things. From what I can tell from the log it is world gen/chunk related so I'll try backing up your world and trying to find out that way if the '1 by 1' didn't do anything.
