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?

Details:
    Block: buildcraftenergy:fluid_block_fuel_gaseous_heat_1[level=1]
    Block location: World: (211,83,950), Chunk: (at 3,5,6 in 13,59; contains blocks 208,0,944 to 223,255,959), Region: (0,1; contains chunks 0,32 to 31,63, blocks 0,0,512 to 511,255,1023)

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:

Details:
    Block: buildcraftenergy:fluid_block_fuel_gaseous_heat_1[level=1]
    Block location: World: (212,83,950), Chunk: (at 4,5,6 in 13,59; contains blocks 208,0,944 to 223,255,959), Region: (0,1; contains chunks 0,32 to 31,63, blocks 0,0,512 to 511,255,1023)

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

    Block: buildcraftenergy:fluid_block_fuel_gaseous_heat_1[level=3]
    Block location: World: (213,83,948), Chunk: (at 5,5,4 in 13,59; contains blocks 208,0,944 to 223,255,959), Region: (0,1; contains chunks 0,32 to 31,63, blocks 0,0,512 to 511,255,1023)

So what is the source causing this?
