Plot Protection Perks!

Plots protect property.
They are designed to stop other players from changing or using protected land unless they have permission.
What Plots Can Protect
Depending on permissions, plot protection can affect:
breaking/placing blocks
trampling farmland
opening containers
using doors, trapdoors, gates, buttons, and levers
using items on blocks
using buckets
interacting with armor stands, item frames, and paintings
interacting with entities
damaging hostile and passive mobs
damaging players through PvP settings
vehicle access such as boats and minecarts
fire/block burning and explosions
natural hostile mob spawning
tree and plant growth crossing plot boundaries
Plots Are Not Full Safe Zones
You can still take normal Minecraft damage inside a plot and die.
Horses
Horse access still depends on ModN Equine horse permissions, not on /plot panel permissions.
If You Cannot Perform an Action...
If you cannot do something inside a plot, you probably do not have the required permission.
Ask the plot owner to check your member permissions, or contact a mod via a #support-ticket on the discord, or by typing /ticket create (comment) while online.
