How do I keep a claim from resetting?

Yolju, manevilus and I are on Civilization. Right now Yol is working. And manevilus is out of the Country for a Month. He is trying to pop on, but is using a laptop. I noticed last night, that I got an alert that his claim will reset in 7 days. We need to reset his claims so he, and we, do not lose it

 

Hello, if he is online for at least 5min it will reset the timer if he is unable to login for that period, put in a ticket and a Sr. Mod will assist you and transfer the claim.

 

Thank you.

 

it would be much easier, if a simple login would be enough.

 

when in the game type /absence

 

still no idea why my claim got deleted then. That seems about right.
