Instanced world - chunk respawning

[Scratch741]

Hello! Your plugin works really well. But I've found one thing. It's not bug but for me it is an issue.

When a player enters a dungeon, he has to click on sign. This sign will spawn monsters and removes gate. The issue is - when he goes really far or he dies, the starting location will reset. That means he has to click one more time on sign and he will double-spawn monsters.

Is it possible to make an option to disable updating chunks like that?
Thanks!
