I'm experiencing an issue where I am still in Essentials vanish and whenever I try to turn essential's vanish off, I'm turning VNP on/off since the commands are the same (/vanish)

I don't see any config file and cannot seem to find any other fixes. Is this a known issue?

first off, essentials vanish has an alias, /evanish.
second off, it turns off if you log off and on
are you sure essentials vanish is on?

Yes, I'm sure it's essentials. I was unaware of the /evanish alias and after using this to turn it off in the worlds affected, everything seems to work fine, thanks for mentioning that.

I'm not sure if multiverse has anything to do with this but it might be. This issue seems like it only happens when you first add VNP after already having essentials and multiverse. Installing the plugin while you're vanished (essentials) may have been what caused this.
