Game crashes on world start up

[Suphy11]

So i was playing yesterday without any problems, closed the game normally and closed the launcher. Today, when i tried to boot up a world, the game crashes, and i could figure out what the problem is. Last thing i did, was sieving moon stone. I haven't installed any new mods, didn't take any mods out of the mod folder, played the game like i always played and i never had that problem.
Tried to create a new world and there was everything fine, no problems while closing or opening the world.

Crash-report:

Chisel: Errors like "[FML]: Unable to lookup ..." are NOT the cause of this crash. You can safely ignore these errors. And update forge while you're at it.
EnderIO: Found the following problem(s) with your installation:
* An unsupportted old RF API is installed (1.7.10R1.0.0 from Minechem-1.7.10-5.0.5.406.jar).
Ender IO needs at least 1.7.10R1.0.2 and will NOT work with older versions.
This may have caused the error. Try reproducing the crash WITHOUT this/these mod(s) before reporting it.

this happened to me a while ago lol. i fixed it by goind trough the world's files and deleting the quest data, then used creative to get my quests back.
