I've gotten such a list of questions, I decided to put them all in on place, so as not to flood the forums. Even if all my questions get answered, I'm sure I'll have more soon!
When you reply please state which question(s) you are replying to.

1. In one of my tribes, I have 2 of the three huts, and all the feathers collected. What is my maximum population?
2. When you finish the feather collection, your maximum population goes up by five. What happens when you complete the other collections?
3. When my villagers finished clearing the rubble, I seemed to start getting tablet pieces less often. Is that normal?
4. Clearing the leaves seemed to go faster than the other building projects. Is that normal?
5. What is the average age for a healthy villager to die at?
6. Sometimes, when I try to make a potion, all the herbs get put in, but no potion appears. I know it's not blowing up. What's happening?
7. One of my villagers once said she was "Praising", and she walked over to some random spot and started doing funny motions with her arms. What are the cause and effects of this action?
8. Will my farmers ever catch anything besides crabs and silvery fish?
9. Are the paralysing effects of the gold berry x3 potion permanent or temporary?
10. I'm worried that one of my tribes is going to end up all black-haired. Is there anything I can do about that?
11. Is there any way to know whether a child will be male or female before they turn 2?
12. Is there a list of all the events and their outcomes? If so please direct me to it!
13. Which hut is the sewing hut, and do you need lvl 3 science before you can access it?
14. What does the sewing hut interface look like? How much does it cost to change the clothes?
15. I've built 2 of the huts, restored the bath, cleared the rubble, and cleared the leaves. Is there anything for my builders to do until I get lvl 3 restoration?
16. Is restoring the statue like restoring the bath, or more like fixing the lift (timewise)?
17. Most of my puzzles say they were completed in 800 or more Isola years. Is this a glitch, because I am only just now getting into my 2nd generation!
18. What's the difference between Easy, Normal and Hard? Can you change mid-game, or do you have to pick at the beginning?

Thank you very much in advance for answering my questions. I apologize if anything I have said is against the rules.

5. That depends on what level of medicine you have. with level 3 I had a villager live to the age og 96!
9.temporary(I think)
10. I don't think so, but you can try "breeding" any blond or brown-haired people to try to get other hair colors.
11. no
12.yes, and it's in the forum that is called "The Secret City, Game Giude' or something similar to that.
14. It looks like an ordinary hut with clothes hanging off it, and they cost about 5000 tech points
15. no(If you want more builders, you should breed your current builders
17.it's probably a glich

1. The max population will depend on the faction you choose. Basic for each
Nature=90 (plus 5 for each collection and 5 for all the collections would be 115, and if you are lucky enough to get triplets when your population is at 114, 117 would be the absolute max)
Magic=100 (plus collections would be 125, and triplets at population of 124 would give 127 for absolute max)
Not sure if you can get events that add to the population when you are at max or not. If so, that would be the only way to go beyond.

2. Finishing each increases population by 5, plus an extra 5 when you finish all.

3. You will only get the tablet pieces once. Since the collectibles are random, the fewer you have left to collect, the less often they will appear.

4. I haven't paid attention to the length of time, but it may be faster. Certainly faster than the bath.

5. That will completely depend on your level of tech and on your faction.

6. Have not seen this happen.

7. "Praising" "Complaining" etc are random acts. You cannot cause them and can't keep them from occuring occasionally.

8. Nope. That appears to be the only food in the ocean.

9. Have not tried that one, but I would imagine they are temporary. Other potions are temporary.

10. Choose to mate the blondes, the furthest on the head/genetic chart apart. But even then there is a certain randomness.

11. Nope. No way to know gender or name until the mother lets them go.

12. This link in the guide section has a few player compiled lists of events. They may not be complete or completely accurate. There is no "Official" list.

13. The foundation will appear when you have level 3 in Science and Restoration.

14. It looks like a hut (different from the living huts) and costs 5000 tech points to change an outfit.

15. You can have them "Fix Huts" to increase their skill. They tend not to be too industrious though and will require a lot of babysitting.

16. Depends on how many builders you use.

17. Have not seen this. May be a glitch?

18. Not sure. I only play on hard.
