Just wondered if you lost your plot if you don't log in the game for a couple of months?

If you let your sub lapse you will get an email letting you know you have X amount of time to resub before it will be taken. if you have a paid sub and do not log in no they will not take it away.

is it hard/expensive to rebuild plots? - it seems a little silly that they take your plot from you

If you knwo your leavinbg you have 2 options. Sell the plot to someone tha will hold it for you or Decon the plot. You lose only 10% of the resources used to make it. Which is not to hard to replace. The rest will go into your vault and can be used to rebuild it. Also if your leaving for a very short term due to money issues. Submit a ticket and they said they would try to work with you.

ah, that makes more sense if you can deconstruct the plot first:)
