[ruifung]

Test again with 2.6.4 and see if its still happening. It shouldn't.

[ruifung]

And besides, that error is saying extra cells can't even find one of its own classes.

im still getting the same error latest.log

[ruifung]

Could you post the actual crash report mentioned in the log?

[ruifung]

I have attempted to reproduce it with a minimum mod install on a server, I am unable to reproduce it.

Perhaps its some class transformer (another coremod) that is breaking it?

[EnhancedC]

This the one? crash-2019-10-19_14.57.24-server.txt

[ruifung]

I see you're using 2.6.3. Please try with 2.6.4 and let me know if it helps.

EDIT: Even using 2.6.3 version that is currently uploaded to curseforge, I am unable to replicate the issue.

EDIT 2: Can you reproduce it with a BARE MINIMUM INSTALL (Nothing but AE2 and extracells only?) If that doesn't crash, start adding mods until you find the one that causes it.

Ok i found out when i removed 'More commands' mod it successfully launched would you have any idea why, all it did was add more commands

[ruifung]

From a quick look at the source of that mod, it does seem to be tampering with the class loading and doing some level of bytecode manipulation.

When I installed in on my test server it crashed with a class not found.. on "the one probe". I'll chalk this up as MoreCommands doing some class loading trickery causing stuff to break.

Just FYI, I've seen crash report issues on the issue tracker for that mod referencing spongeforge, immersive engineering, vanillafix... so yeah...

EDIT: I've tried a ABSOLUTE minimum setup with only 3 mods: AE2, EC2 and More Commands. That seems to start fine. Looks like the presence of MoreCommands along with another mod / mods / coremod is mangling the classpath / class bytecode. Nothing I can do on this one.

Why on earth does a mere "command mod" need to do classloading trickery is beyond me.
