Steps To Reproduce:

1. Updated FTB revelation from 3.3 to 3.4
2. Opened game to check if it works
3. opened blue /dank/null and all the items were missing

Was this tested on Single Player or Server (or Both)?

Server

Was this tested with just Dank Null installed, if not what is the minimal set of mods to cause the issue?

234 mods in total in game

Please let me know if you need anything else. Thank you.

Also ran into this issue, looked a bit further into it

This is expected, as one of the previous changelogs for /dank/null/ has it as wiping inventories (looking at the NBT tags for an old and a new /dank/null/ the data structures are different, so likely it just isn't able to read the old information)

If you have access to the playerdata from the server I would suggest downgrading to 3.3, extracting everything out of the /dank/null/ (the data is still there from the looks of it, unless you have backups in which case all the better) upgrading to 3.4 and then transferring it back through some other form of storage, like a creative refined storage/applied energistics
