TradePlus not working after updating to 1.16.5

[MilesBHuff]

I paid for the plugin, and am running TradePlus v3.81.0. It does not work on my 1.16.5 Paper server. Players run /trade, and no trade window appears. Worse: players become frozen in-place, unable to move until they relog.

The issue also occurred in version 3.79.2, which is the latest version available on GitHub; but players weren't frozen in-place.

Hey, I literally paid $7.50 for this plugin, because it wasn't working. A reply would be nice.

I will do some testing with latest releases of 1.16 and fix the issue soon. Sorry for the inconvenience.

Thank you! Worth noting: I'm on Java 16. I have a suspicion that that is why; but I'm unable to downgrade because some plugins require it now.

Just updated to the latest version on the Spigot website. Plugin is still broken in exactly the same way. I paid you $7.50 to fix this half a year ago. What is going on, lol. Players are upset and there's nothing I can do.
