[2020] Bug in settlement migration (9.0.10)

Hello,

I have a colony of 20+ humans that I migrated (with 7-8 children), and noticed a few things.

1/ Upon arriving to the new location, I am notified that all the children are waiting for a profession. Indeed, upon opening the settler list view, the profession icon is selectable, the same way a child that has reached adulthood. However all these children are younger than 15. Upon save and reload, the UI reverts to normal (ie the profession icon is not clickable).

2/ These children all became "orphan", that is they don't share a bedroom with their parents anymore, even if they are still younger than 15.

3/ I migrated at the start of summer (not even far away, probably a few tiles), and was expecting upon arrival to still be in summer, but the game calendra restarted the settlement on spring, which did not made too much sense.

(Is there a proper channel for reporting bugs, or reddit will do? I looked briefly at the Trello, but it looked more like a dev dashboard than a bug reporting place)
