[Bug]: Client Disconnect on Both Single and Multiplayer

[msj34]

Possible Fixes

Yes

Modpack Version

2.35

What happened?

This crash happens on single player as well as multplayer. I have gotten the same exact error on version 2.34 as well as 2.33. Have not tested 2.32. Not sure if this is related to the known issues list. If this is you can remove this report as you are aware of it.

Note this does not generate a crash log rather an entry in the debug folder with the file name disconnect_xxx_xx_xx_time-client.txt.

Edited to reflect that this error also occurs on 2.35.

I found this might be related to Modular Machinery Reborn Mod. Specifically I have gotten to a point of setting up fissile fuel creation with all the steps in the form of their multiblocks. What makes me think it is their mod is this point in the error log it only calls out this mod. Caused by: java.lang.RuntimeException: Failed decoding custom payload modular_machinery_reborn:update_chemical: java.lang.IndexOutOfBoundsException: readerIndex(47) + length(8) exceeds writerIndex(52): PooledUnsafeHeapByteBuf(ridx: 47, widx: 52, cap: 256) I have combed through the logs and I have just removed the controller block for the entire process and so far appears to be stable. I can go one by one down the crafting chain until I find which one causes the disconnect. Though this will have to be later in the week due to work.

Note the Runic Crucible Multiblock and the Automatic H forge so far seems to not cause the issue either.
