This feature creates a major security hole.
How the hole works is this:
1. Land baron #1 sells island with EO rights to another person. The EO is approved by LL, but the Land baron remains payor.
2. Tenant goes to Land Baron #2, adds them to allowed residents list.
3. Land baron #2 drops islands around the first island, thus reducing the value of the island.
4. Tenant goes to Land baron #1 and extorts rent decrease.
There needs to be a check in this feature to make sure that the person who has EO is also payor.
