The server doomed after opening it wrongly with .jar but not .bat

[philip9876]

Every day I open the server with server.bat and it works perfectly. Today I accidentally open the server with minecraft_server.1.12.2.jar and the world loading is extremely fast compared to opening with .bat.

Then I close the server and open it with bat., and then it crashes immediately after loading the world

Next I found that forcechunks.dat and level.dat have been changed.

Hope my world isn't corrupted. Anything I can do to save this?

Ok I find out the problem
However I remember I haven't built any buildcraft stuff in that area

After I delete the block in MCedit, the crash report:

I change all the blocks near that block into stone and the crash report becomes:

So what is the source causing this?
