NBT Data Packet Overflow in Bag
Unknown-88 opened this issue ยท 4 comments
If you put a large amount of NBT heavy items, for example about 60 full ae2 disks... Well this happens. I know this is not specifically the bags fault, but potentially it could stop excepting items if it is approaching the limit for too many nbt tags?

I need more than just the exception stack trace. This tells me nothing about your mod setup/etc
I am running the latest version of the DW20 pack, with ee3 0.3.505, when I filled an achemical bag with to many items with lots of NBT tags, the server could no longer sync my inventory. Using an nbt editor I found the bag had about 12000 nbt tags in total, I deleted one ae2 drive from the bag, which contained exactly 120 tags, and then was able to rejoin the server, as the packet was no longer above max size. I am aware this is my fault, just thought i would let you know this can happen.
A possible solution to this would be for EE3 inventories we could compress NBT tags on items when we save the inventory. This would make opening/closing the inventory slightly slower, but would reduce the total size of the object and avoid this issue.
