Can't join server
I'm having problems on my own server with joining. As soon as world gets loading I'm getting this message: "Connection Lost Internal Exception: java.lang.NullPointerException: Cannot invoke "net.minecraft.nbt.CompoundTag.m128437(String. int)" because "nbt" is null" . If I join with mods only from server (without client sided mods e.g. Embeddium, NotEnoughAnimations) it works fine. However I tried binary search on client sided mods and it theoretically worked. I disabled some mods like Apple Skin, JEI and it worked but if I add any other server sided mod like Too fast I cannot join again. I saw also this post - https://github.com/Creators-of-Create/Create/issues/6032#issue-2103356614. The funny part is that it looks like disabling Steam and Rails solves this issue. I could do binary search from mods on server but I do not think it will help that much because this issue is pretty inconsistent. Would anyone have any suggestion what to do?

Try with just steam n rails + create, slowly add mods to find out what causes it
I've tried multiple times to reproduce this and the best conclusion is something has a bad Mixin that either conflicts with create or steam n rails and causes it
Since it doesn't happen with just create + steam n rails
Should I only add client and server sided mods (e.g. new blocks)?
I may know what is happening. I just made a new world and didn't get an error. However I placed train station and got kicked out immediately with the same message error. My theory is whenever I quit from the server with train station loaded I cannot join back. File is from debug log. Are these mixins broken? Disabling Create Copycats, Connected and Destroy didn't make a difference.

Add a few mods and see if it happens
And then remove a few until you figure out which mod causes it
I have founded it. The issue is with Create: Power Loader (https://modrinth.com/mod/create-power-loader). I had only Create, Steam and Rails, Kotlin and chunk loaders. Should I report it to them on Github?
Yep
Actually it's more complicated. Chunk loaders with Create and Steam and Rails works fine. Create New Age with Steam and Rails works fine. Create with Chunk Loaders and with New Age works. However Create, Steam and Rails, New Age and Chunk Loaders don't work. What should I do now?
Power loaders
They've got some mixins that are adding data to create stuff and somehow messing it up
