Sponge will not load map

Okay, so my spawn map was working wonderfully on sponge for the longest time. And now today when I started my server, I kept getting errors and my friend who helps me build couldn’t connect. So I tested my world on single player, loaded perfectly. So i thought the server just must have gathered junk in the server files. So i got the latest build (514) and installed the server perfectly, and then stoped it like you should. Then I installed the world just like I did before, by deleteing “world”, adding my “Spawn” world and changed the map it loads by default in the “server.properties” and again got the same error. This is my crash log.

well your getting an End Of File Exception meaning there is a read issue on one of your files, can you post your server.properties file here

Do you do regular server backups? Have you tried using the whole backup instead of just replacing the world? Like Azewilous said, it is very possible that it is an issue with your properties file. Also what does it say when your friend tries to connect (on his minecraft client)?

Either the file level_sponge.dat or level_sponge.dat_old is corrupt.
This shouldn’t happen under normal circumstances. Did the server crash or stop suddenly at some point prior to this?
If you don’t have a backup of the file, delete it and it should hopefully regenerate (Remember to keep a backup before deleting, in case more things break)

@Thorns_Ofire & @Azewilous Here is my server.properties, and i will try and fix the level_sponge.dat @simon816. And my PC power was shut off in the middle of playing Left 4 Dead 2, but I didnt think the server was running when my PC got shut off, it must have been.

I removed all of the level_sponge.dat & level_sponge.dat_old and it worked again. Thank you!
