Thanks MissKathy.
I have been on vacation. Meanwhile I reached a point in the game where it is no longer such an issue. I only run it for short periods now and do no longer use most of the powers. Still seeing whether I can make all the trophies and still having three to go:
- All you can eat (84% completed)
- Never a dull moment (36% completed)
- Rub those sticks together (28% completed)
Also now have 68 JoaTs (61% of my entire tribe) with the other 42 on 5 masters each.
