Advanced Town Builder

I continued the test. I manually altered the capacities of the towns. What happened is:
- the towns with no ind/com only grew to match their new basic size and not target pop
- in one of them I was able to create a com zone, by setting it at 500 and waiting 8 years (!); the town had 2 (!) shops and its pop still did not grew past the basic size
- the towns with ind/com grew as they should as soon as the new caps were set at anything above 50, but then they did so at a much slower rate than the organically planted city
- I could completely remove ind zone in one of them, but not recreate it
- the sliders for zone sizes worked for the organic town just fine

I think a bit more information won't hurt.
The towns I tested were indeed very small, 30-40 residential with 0-20 industrial and commercial capacity. The other, the one plopped by the vanilla tool, had caps of 135.
I placed them in the map editor, not after the game started; I know it makes a difference for some assets.
I did not test your tool on bigger towns yet, but I'm about to.

Yes. The medium size town I plopped for the test as a control group grew normally.

Is the behavior different than towns placed with the official town placer?

The towns spawned by the tool do not grow. Is this intentional?
I ran a test game with 4 very small towns, I supplied them with everything they needed over 5 years and even though they showed that their target population should increase by 140%, they stayed the same size.
I had two somewhat realted mods that could potentially interfere, namely Town Tuning and Urbanization, but after uninstalling them the issue persists.

@MrTarakan you have to adjust the Industrial and Commercial volume sliders too.

а) was completely uncalled for, i was just asking how to prevent that from happening without delivering demand, but thanks for information

a) complain about the weird town dynamics
b) fulfil town's needs to trigger growth
c) increase base capacities using sandbox
d) ask somewhere else as this a general issue not limited to this mod

what can i do about it?

That is a subsequent action from the town expansion algorithm adjusting base capacties to target
