I'm been developing my plugin lately and i have hit a strange bug. After adding an update to ACF and some new APIs i began to have issues with worldguard, worldedit (That i solved editing the API since they don't support outdated versions) and after solving them i have gotten this one with vault that forces me to go to the drawing table. I do not know why I'm getting this issue and why the hell do Vault check permissions on bpermissions when im using Luckperms. Any help?

This isn't a Vault issue. this is a problem with one of the plugins on your system trying to make calls into a permission system that doesn't exist. looks like either dchat, or whatever is at com.extendedclip.papi.expansion.vault.VaultPermsHook.
