Inactive

From Toadwater Guide

An "inactive player" is someone who has been logged out of the ToadWater Client for at least 1 diddy.

The square that an inactive player is standing on is considered occupied. However you cannot see the player and you are able to walk on top of that square.

An inactive player in your base can suddenly become active and steal your stuff. To prevent this consider using sharpies then using BVs on all inactives you find (a difficult and time-consuming task).

See occupied for more info.
