A while back a change was made to water barrels, because people were exploiting them to assist in house placement. These are the things that are currently being exploited to assist "some" people in obtaining there own pre known house plot size, and blocking everyone else. Corpses, (players or animals) block house placement. Blood Splatter. Noob characters whacking horses splattering blood all over a plot area. Carpet tiles. (not really used by anyone, as it depends on whether or not the house that fell has them, but its still annoying.) Please look in to this. Thank you.
