When I run the new mixed+hs-v23-ipv6 chutney network from legacy/trac#33333, I see the following warning: ``` Ignored cell (40) that arrived in padding circuit 32. ``` I am running Tor 3.5.8 and 0.4.4.0-alpha (a6509cb867). This issue appears to be timing-dependent: I saw it on one run, but I did not see it on the next one.
