**Motivation** A bug was found on hoodi that needs to be rectified. 1) 1st column arrives via gossip 2) trigger getBlobsV2 3) many more columns (but not all) come via gossip 4) gossip block arrives 5) reqresp triggered via block arrival 6) get remaining data via reqresp 7) process blockInput 8) delete cached blockInput 9) remaining columns arrive via gossip and get added to a new BlockInput 10) getBlobsV2 finishes and gossips "missing" columns not found on new BlockInput 11) reqresp gets triggered again after timeout (from second batch of gossip columns on second BlockInput) 12) second batch of columns and second block get reqresp downloaded and second block Input goes for processing --------- Co-authored-by: Nico Flaig <nflaig@protonmail.com>
