Expected behaviour

Erigon unwinds to the point of the fork, downloads the correct blocks based on the hashes obtained from the CL

Actual behaviour

Erigon is stuck on 

[EngineBlockDownloader] Could not insert headers and bodies err="missing body at block=30181"

even if downloaded blocks around the stuck block height

Steps to reproduce the behaviour

Let an erigon client fork for some reason. Stop it, restart it after some time.

that could be due to invalid blockbodies file for required range, remove them and restart just to see if case persists, you are just 30k blocks away from 0.

It will probably work, but the node should be able to auto-recover from this situation. Also, it can be expected of the node to not be stuck with a missing block body and download it from the network. There is a bug somewhere in the downloader
