It's possible to change the color of the grass in a Worldguard Region
To reproduce this, all you have to do is be in a Worldguard Region and place a Powder Snow Bucket.
(If you're admin, make sure that your /rg bypass is disabled)
Expected behaviour is that the grass shouldn't change color.
Relogging does not fix the issue, confirming that the block is changed server-side.
The worst part about this is that it isn't logged by CoreProtect.
It's also important to note the server is running an outdated version of Worldguard, it's recommended to upgrade to 7.0.8 (server is currently running 7.0.6)
