The 9 mods i have are Cars and Drives Mod, Little Blocks Mod, Instant Massive Structures mod 2, Build faster mod, Compact Chests, Dynamic Surroundings, Minecraft Flight Simulator, orespawn, and Reis Minimap.

Help would be very much appreciated with how much I have done on this world.

what is the newest forge for 1.7.10?

ok, so i have been messing around now and I figured out it was the flight simulator mod crashing it. would you think if I deleted it and reinstalled it, it would work?

You can try to reinstall a new version of it as in it could be a new version for forge 1.7.10.

This did work. Thanks for the help
