Can be fixed by downgrading NEI to NotEnoughItems-2.3.47-GTNH

Crash when try to join second time a world(ON SERVER) :
crash-2023-05-10_19.27.30-client.txt

the modpack :

Thank you, that was very helpful. I think I have a fix. Can you please try the following jar (within the zip file) and let me know if it fixes the crash?

NotEnoughItems-2.3.51-GTNH.bigpack.fix-1.zip

I am starting the game, let's wait

i maked alot of test(like 4 or 5 hours) , and every time i make a new test , it seem that not same mods are suspects , so i think its a bug in NEI

This is a hardpass to support, that pile up of mods has some invasive mods, mods which purposefully don't work with gtnh codebase and a lot of conflicting and poorly written mods.

Do some diligence and find which mod causes conflict at least. Better if you can point at which change between NEI 47 and 48 caused that to conflict.

Use that special given version, it was modified to provide more debug information on the crash form nei side. Its not the same as normal . 51

crash-2023-05-10_16.15.29-client.txt

ah ok

I've tested the changes from 2.3.48 with GTNH and didn't hit that. Your modpack has 800 mods, which sounds crazy to me.

I need a bit of cooperation from your side to be able to narrow this down. Can please try out the following build of NEI 2.3.51, which includes a couple of additional log statement?

NotEnoughItems-2.3.51-GTNH.bigpack.crash.debug.zip

Please try to replicate the crash and upload the full client log.

i tried the latest 2.3.51 but didn't work , only work with 2.3.47 and before

This is a specially modified version.

normally i have a crash report with 2.3.51 i will give you

This will not be helpful. Again, the jar I've linked to above has a couple of additional log messages, that might help me narrow this down.

Also, I need the full client log not just the crash log. The crash log does not have all the information I need.

i just need to change the Nei version to this version right?

You have to manually replace the jar file locally in your instance's mods folder. (no changes necessary on the server)

ok so l'ill try it , and i will give you crash report + fml-client-latest.log

Here is the crash report + logs with the debug

crash-2023-05-10_21.03.35-client.txt

fml-client-latest.log

it seem the same crash occur

wait , its seem that fixed it , i crashed and i tried to rejoin the server and seem to be work. so idk

edit : i think it save in memory the last config reload from the previous crash with the 2.3.51-debug, i tried to remaking a server world and it seem that don't crash anymore.thx

Hmm, that doesn't give me a lot of confidence. Can you maybe try booting the server and client fresh again? Make sure you have the latest jar that I've posted above installed in your client instance (....bigpack.fix-1.jar). Then connect to the server once and then a second time.

If it crashes on the first connect, please post the crash log here anyway, It may not be related to this bug report, but I still want to make sure that it isn't related to some other issue in NEI... With 800 mods, you can expect things to be weird.

wdym by booting the server and client fresh?

I mean just stopping both client and server and starting them again.

i have the .bigpack.fix-1.jar in both

1 : i relanched both

2 : first time joining server world , all is okay

3 : second time joining server world , all is okay

4 : some time joining server world , all is okay

to make sure that isn't chance , i will relaunch again server and client

Test 2 :

i have the .bigpack.fix-1.jar in both

1 : i relanched both

2 : first time joining server world , all is okay

3 : second time joining server world , crash :
crash-2023-05-10_22.13.26-client.txt
fml-client-latest.log

4 : some time joining server world , all is okay

So its better than before , like just one crash , not all time crash when try to join server world , it's really less anoying

Thanks. OK, so it's still the same issue. Can you please upload the full client log?

EDIT: Thank you.

ok

OK, here is my second attempt at a fix. Please try!

NotEnoughItems-2.3.51-GTNH.bigpack.fix-2.zip

So i relaunched three times client and server and maked test , and it seem that crash is fixed.Thx.

Great to hear. A proper NEI release with the fix will hopefully be made soon.

ok Thx
