Thanks for reporting this, @elitan.

I'll check this ASAP.

Just before I check this, what Atlas version do you use?

[elitan]

❯ atlas version
atlas version v0.30.1-980b47e-canary
https://github.com/ariga/atlas/releases/latest

Renaming a column and changing its generation expression caused this issue. The issue was resolved and a new patch version should be released soon.
