Hi, I want to use this plugin for anarchy survival 1.15.2 server.

But i've got a problem. I can't find the flag which allows to push blocks with pistons,which are placed outside the field. So players can't grief regions with pistons.
Is there any analogue of WorldGuard 6.2.x piston flag, which allows such things? Is that possible on this plugin?

Hey this is the new github page of the plugin: https://github.com/elBukkit/PreciousStones ; There we are active and also you will find the latest stable version!

I dont think there is a specific flag for that, as far as I remember, prevent-destroy is the one which protects pistons from the outside to steal stuff.
