Hi, I have an issue.
When I launch my Tekkit, it takes forever to load, and when it does load, it is very unresponsive and laggy and jittery. It will pause for a few seconds, then resume for only a millisecond, then keep on pausing and etc. When I go into my Tekkit world as well, it does the same thing, but my character is very slow and doesn't move until the millisecond resume period comes back, and even then my character rubber bands back to the spot that I wanted to move away from. There is intense frame skipping, and when I hover over any option buttons, it takes even a couple seconds for the game to register that I'm hovering over the button.
I've done research on it and found many things that I'm just spit balling what they could be. One post said it could be something to do with java, which I found at this website http://www.technicpack.net/article/concurrentmodificationexception-in-java-18020.89, but I don't know what they are talking about there. I also looked through the log, and found warnings that had things like "missing textures" or "[modpack] did not have tag 'version' with it" or something like that. I'm not very knowledgeable about code and understanding logs, so this is very confusing to me. I will post the link with the log so anyone can feel free to take a look at it. If you could that would be very kind.
