Hello,
It seems that the bug in which the goods are not unlocked if the population tier reached 0 is still not fixed, even in GU 9.3:

As you can see, I already have investors there, but the needs for engineers are still locked, even though I had them unlocked before.
I tried testing further, and placed a farmer residence, lo and behold: the needs are still not unlocked

This appears as a bug fix in the release notes, but it doesn't seem to be the case.
PS: Yes, I re-verified my files after the update, and same issue.
