EssentialsX version (/essentials): Currently on #532 version on jenkins, I believe we were on #528 before I updated today. This started happening Monday after no changes were made to the server. It is still happening on this latest version.

Server software (/version): spigot-7754231-94b0980 1.12.2

This suddenly started happening after nothing was changed on the server. The towny creator instantly said its essentials. (TownyAdvanced/Towny#2704)

Sure thing, first post updated with error in pastebin

I don't mean to be annoying but bumping this up again. This has almost fully broken towny for us.

Could you try replicating this on a test server with just Towny, EssentialsX and Vault, both with and without your server's user data on your test server?

Done. I was able to recreate with the server data on the test server. I cannot recreate without the data
