Hi there, I had 64 territory cap for ROC and now I log in only to find I have only 55, why is this?

I would guess that you had the event benefit package that gives you an extra 10 plots but it has run out.

The territory cap increases by one every day for the majority of the event. And you can add to this with the investment package giving you 10 extra. The package only lasts for 1 week though so you either have to renew it or no long have access to the extra capacity.

If the plots are occupied then you will not lose them but you won't be able to occupy any new ones until you drop some or you wait for the capacity to increase.
