Hi,

I playing minecraft for a long time and I have a very nice world but the worst thing happend. Some zombies killed me and when I tried to respawn minecraft crashed. I worked a long time and very hard on this map.
I have only a backup of it from two weeks ago. But in the meantime I added already alot of building...

I made a copy of this world and tried to find out how to fix this problem.
It worked for me to delete the level.dat and session.lock and I can spawn again but I found out when I explore new areas they don't connect with the old world.

Could someone help me wit this problem, how can I fix it without losing my map and getting strange borders around my map.

The only mod I use is Single Player Commands.

Thanks for reading.
