Automatically check and prune data if NBT is too large

[SecretlyJealous]

This issue is becoming increasingly common on my creative server:

When a player has too much NBT data they are no longer able to join the server and need an Admin to reset their data, the problem is that this happens so frequently on creative mode that instead of having to wait for an admin to reset this data I was wondering if it was possible to add some sort of option in the plugin that would just delete the data when this situation occurs? Because the only way to fix this would be for the Admin to delete the data either way.

I'm on HuskSync | v3.8.7

Hi, you should be able to delete snapshots using /userdata list (name) and then clicking through to delete?

Hi, you should be able to delete snapshots using /userdata list (name) and then clicking through to delete?

This issue happens every day with multiple players though, and those players have to wait for an Admin to use that command. We've had to remove the plugin because of how frequently this issue happens. Unfortunately waiting for an Admin to delete the snapshot is not practical when this issue happens so often

[WiIIiam278]

Alright, I'll change this to a feature request to check this

[Emibergo02]

it doesn't seem to be a size issue, but a malformed json issue. there is probably an escape char or something that is messing with the Json deserialization
