New Town Guide

Either I'm just not finding it and it's already in the guide, but I can't see any info about town cost and days to build?!

The cost is 39,000 and it takes 3 days.

Level 19 gives 1 diamond
Level 19 to 20 requires 17381 rep points.

Level 20 gives 10 diamonds
Level 20 to 21 requires 19550 rep pts.

hi,
when i wanted to upgrade the buildings, i could do it 9 times.
i upgraded the speed to its max of 30%, and the coins to 15%. then i had to wait for level 16 in order to continue upgrading.
does anybody know if there is another limit of level for the rest of the upgrades ?
i am guessing that the max upgrades will be 30% for each (time, coins, xp), the question is how often u have to wait for a certain level to continue with the upgrades.

if you are rep lv 15, your max building lvl is 15. When you level up, you get a message like 'You can now upgrade all town buildings to level xx', isnt it?

level 21 - 1 diamond
21 to 22 - 21778 rep pts

What is the advantage of upgrading all the buildings to their maximum? Has anyone done it? Looks like it would take forever to collect all the things to do them all. Also all the bricks and paint pots are clogging up my barn!
I for one am now fed up with the town, I have all the buildings, so nothing to look forward to. The little people are not paying me enough for the goods. I sent most of them away today as soon as they got off the train. I just couldn't be bothered with them all.

Reaching Level 23 you just get 1 diamond,

and it's 26,336 rep points to get to level 24.

Level 24 - to get to level 25 it is 28 630 rep points

edit - Level 24 is the last level you can upgrade town buildings, everything is now greyed out.
