So I previously found that all sub plots (first level and nested) inherited the flag values set on the parent plot (aka the town) Originally my town was set to "block-break -g nonowners deny" which applied to the town, the buildings, and the plots inside the buildings etc. This prevented players from breaking blocks unless they were the owner of plot. I would add people as owners to the plot which allowed then to build and break within their plot, but as members of the building (due to irregular plot shapes) and to prevent grief to habitable structures. I've noticed since TC3 was added this only applies to the town and the buildings, any plot that is nested 2 levels below where the flag was set doesn't inherit the flag anymore. In fact for anyone to break blocks in the plot they had to be added as an owner to the building as well My attempt at illustrating this: My Town Avalon (/rg flag block-break -g nonowners deny) My town building townhouse2 (inherits the flag set on the town) [full world height] My builder plot th2-2b (does not inherit the flag, has none set) [7 x 7 x 3] I've had this happen with multiple users in the same area. the original set up underwent a lot of testing and was working as intended until i went to add a new player a few days ago.
