Player cannot access backpack after winning Survival Event.

Player won the survival event and respawned back like normal. They are getting the "You cannot open your backpack during an event." error after coming back down to the main island. The only way I can get them to access their pack currently is by unloading the plugin. I tried to unload, and reload but the issue persists after it compiles. Is there any way I can clear this 'in event' flag from the player manually?
 

also no new additions of plugins or anything have been made to the server in some time, so nothing should be conflicting as it has been working as intended until this one occurance

This was fixed by unload and reloading the event helper while survival arena was unloaded

I have no idea what is causing the problem. Hoping to find a solution soon. Let me know if you have any info around the events that lead to the bug occurring.
