Destroy Buyout
I find destroy buyout very frustrating at its current state. I had a game today where I bought a player out and needed water. In order to find what water he had on the map I had to scan the entire map and look for the little numbers everywhere. I wasted a lot of valuable time doing so.
I propose that when you buy out a player in destroy buyout that you leave the "resource lines" on the screen for the duration of the tile cooldown so you can track down all their old tiles in remote places. If it's an early buyout and you miss reclaiming one of those valuable tiles then that means you're helping your opponents by giving them free valuable tiles.
