Micrograph thumbnails disappearing for imported job

Hi,

If I export an exposure sets job (with denoised mics in passthrough), then import it on another instance (v5.06), if I run curate exposures on that job, I see correct micrograph thumbnails appearing in Curate.

However, if I run an intermediate job - e.g. junk detector - on that imported exposure sets job, and then run curate exposures on that, it does not show thumbnails in curate. Is this a bug, or am I doing something wrong? You can test if needed with this exported job:

Cheers
