Just writing this down while I'm having my morning cigar and thinking.
New Kingdom Boost
When a player joins a round that's in progress, depending how far we are into the round we can let them go into settings and boost their kingdom to get up to speed faster = reduce protection to 20h, dump resources, dump a pack of houses filled with pez. The goal would be to help a player that joins a in-progress game to catch up a bit faster, so if they missed 3-4 weeks of a round we can get them up and running faster. The option would become available based on a timer, like after a round has been running +3 weeks, and it would only work for kingdoms that are in new kd protection (new kds).
