Minecraft Forums

I am an avid crafter who has gotten locked out of his world. the error report says that the problem is based with an entity. the last time i played i was having trouble with not being able to interact with minecarts. i could push them but not get in them. thinking that this is the entity causing my crash. if anyones has any information on how to fix this i would really appreciate it. lot of hrs have gone into this world and i would rather not have to go to a backup from 3 months back.

also the only mod i am using is magic launcher

Have you tried not using magic launcher to get in your world?
If that does not work you could force update it which only takes out all mods

the most recent crash report looks something like this. also minecraft never logs into the world. it says that it is loading terrain but eventually (after about 20 mins) it will just return to the main window. other saves work just fine, and i have reinstalled minecraft and magic launcher. i am also using optifine.

Have you tried not using magic launcher to get in your world?

yes i have tried using regular minecraft. and have reinstalled everything

Have you tried upping your world save to the Official Corrupted Save Recovery Thread?

I believe IronMagus is correct I'm having the same problem with my ultra craft world on day I'm playing it the next I log in and it's not in any save folder! I put many hours into it Sewell and I need help. PSit won't show up in the .minecraft and I have no mods or texture packs at the moment. >_<

The problem is with the memory being all used up.

java.lang.OutOfMemoryError: Java heap space

Remove the minecarts with something like MCEdit and you should be fine.

used the save recovery thread and got my world back. logged in and out multiple times and everything seems to be back to normal

used the advice in the 6th paragraph and reloaded a previous save from yesterday. everything works out fine. thanks IronMagnus!
