ok so I have 50 totems, and all collectables well all but a couple of pebbles... population at max, when suddenly I get triplets.. so i decide to experiment

age i4... topa research
topaz farming
Tonga building


and I hoped to find/ or not find the speed in which they would gain a master......as My initial hypothesis was:
Topa would reach master first
then Topaz
and Tonga would struggle on to her 30's as Fixing huts is the only option.... unless I had level 3 medicine and triplets before I cleared the vines/mosiac,built hospital and clothes shop all which I had completed before I got trips

all was going to to my hypothesis
age 20

Topa is so close to becoming master
Topaz needs a little bit more than Topa

and I Locate Tonga .....and she is with child

Tonga must have got bored fixing huts lol
