Well the issue:
When you go and edit your review that has screenshots already added (screenshots been there since you've written it), then go and edit the review (i.e. change some grammar errors or rewrite some sections) then submit it, it will remove the screenshots previously uploaded.

Is there anyway to fix this bug?
P.S. Also is there a way to re-apply the screenshots. I'm sure they're still on the MT server, in the directory for review screenshots (whatever you guys have the folder(s) named). I experienced the bug on this review:
