Small fix relating to weaving potions effect which could have spawned cobwebs inside protected residence area. Keep in mind that this protection is based on entities death location and not where cobwebs actually spawn in due to minecraft weird handling of this effect, so cobwebs could still spawn inside residence in case entity died at the edge of it. This might be fixed with later updates.
