I'm currently testing the way custom building grow ingame depending on the asset you took as a template when you imported.
I'm running tests on level 5 high density residential.
I've exclusively made 4x4 lots but taken all lots as templates since you can change the lot size later.
More than half of the resulting lots NEVER grow.
Worse, you might think it's because sometimes I took a 2x2 lot as a template, but no. NONE of the 4x4 templates resulted in growing lots.
Maybe it's random... I won't re-test everything.
I can just advise all builders to ALWAYS test their growable buildings in the game and see if it grows or not. (Especially for high level growables, do not just take a picture in the asset editor and upload your work, take the time to test it.).
