Resources (oasis) renewal

There should be a way to renew your oasises, for example instead of having to grab a different oasis every time it's level is reduced a player can instead spend x amount of resources to get it to it's original level (level it was obtained by said player) or have a tech that reduces decay (usage) of oasises and it's top level can be never reduces level (lvl 1 10%, lvl 2 20%, lvl 10 stays at lvl obtained forever etc)

Right before your 24 hours are up you can resign then add back.

I Like the Tech idea.
Resource Decay Tech: Standard decay is 24 Hours:
Lvl 1 - Adds 10% Time
Lvl 2 - Adds 20% time
.
.
.
Lvl 10 - Adds 100% Time

You can't have Non-decaying Oasis because then a person can crop up, go into Refuse War, and take a 5-day break without worry of cropping themselves. but having a system that extends the time it takes for them to decay would be great...

That is a great idea!
