On the other hand, keeping the continue means that you only run the retry if the last _meta wasn't found, which seems not that accurate. I think we have two options here:
1) save whether we found at least one _meta not found and schedule a retry at the end
2) remove the continue and schedule a retry for each _meta not found

I'd go for option 1) but 2) is not that bad either in this context to me.
