Error on interact with BP in a non allowe interaction (Multiplayer)

[FabioZumbi12]

Hi,

I using this mod in a Sponge server, and with a plugin to deny interaction and block placement in one specific world.

I getting this error on try to interact with a BP ins a non interactable BP, where a plugin cancel the interaction by sponge event listeners:

WBP Version: WearableBackpacks-1.12.2-3.1.2.jar
Forge version: forge-1.12.2-14.23.3.2655

Edit: Testing now and the BP still disapearing when i try to place the BP in a not allowed region, but now without errors, only on interaction.

Besides the error, this is still the same issue as #41? (Should I close that one, now?) What changed that made the error go away? A differerent plugin?

I suspect it might still be difficult for anyone to work around Sponge / Forge when they do something non-standard as I am. I was considering doing #14 but I didn't get around to that. Also I've stopped working on WBs for now.
