Minecraft Forums

If you are reading this with the intention to help me out, thank you thank you thank you.

I've been playing Minecraft for about a week now and have fallen in love with it. That said, I've been having some very frustrating problems that I've been told should be easy to fix.

I started a lan world with my roommate and everything went well until my computer crashed several times and corrupted things. Not knowing what it was, I jumped into a missing chunk and MC crashed and we haven't been able to enter the world since. It freezes loading on "building terrain" and stays there forever.

Then, we started a new world. Things went well but this morning neither of us could log in without an immediate crash. We get the error message "exception in world tick".

After some intense googling, it looks like there's problems with corrupted or missing chunks in both worlds, and I downloaded Mcedit to try and fix it as suggested in several places, but my problem is this: I have no idea how to know which chunk is the problem or find that chunk or fix that chunk.

PLEASE HELP! I am capable of fixing things if I know how, so help me know what to do. I love this game but it will be discouraging beyond belief if I can't get into either of the worlds I spent many many hours creating with my friend.

I can post crash info upon request and also have the saves zipped and ready to be posted if anyone wants to take a look at them.

Here it is, thanks for the help.

some mod in your pack is causing faulty mob spawning. my money is on either LotsOMobs or Breeds{1.6.4 v5} [ModBreeds] (BetterBreeds 1.6.4 v5.zip)
which i see in your log.

in beginning of your post i see Packet24MobSpawn.func_73279
suggesting this issue has to do with your mobspawning. try disabling one or both of these mods.
if the error persists, set your world to peaceful mode and start it again to see if you can wipe the board of mobs.
