@lra Thanks for this report. Would you mind sharing the affected config (or relevant part of it - at least aws_s3_bucket), so we could add it as a test case and prevent this bug from ever re-appearing?

[lra]

@radeksimko It might be tough to find the culprit, and slow, because our TF files are huge.

Looks like you got a good candidate in #1336
