Bug Description

[17:19:19 WARN]: [Multiverse-Core] "Multiverse-Core v4.3.1-b861" has registered a listener for org.bukkit.event.entity.EntityCreatePortalEvent on method "public void com.onarandombox.MultiverseCore.listeners.MVPortalListener.entityPortalCreate(org.bukkit.event.entity.EntityCreatePortalEvent)", but the event is Deprecated. "Server performance will be affected"; please notify the authors [dumptruckman, Rigby, fernferret, lithium3141, main--].

Steps to reproduce

Agreements

• I have searched for and ensured there isn't already an open or resolved issue(s) regarding this.
• I was able to reproduce my issue on a freshly setup and up-to-date server with the latest version of Multiverse plugins with no other plugins and with no kinds of other server or client mods.

This is a well known "bug". As the message directly after your warning states, [17:19:19] [Server thread/INFO]: [Multiverse-Core] §aWe are aware of the warning about the deprecated event. There is no alternative that allows us to do what we need to do and performance impact is negligible. It is safe to ignore.
This issue a duplicate of #2000 and resolved by PR #2557, which is planned to be included in version 5.0.0, whenever that happens.
In the meantime, this is completely safe to ignore.
