I (finally - based on your good reports) reproduced the problem of “recent builds drop some packets / sometimes”.

Alas - I need to do some “life stuff” today. But I should have time tomorrow to use this new logging and find/fix the root bug. Sorry this is taking a while but wanted to give an update…
