Err, can't reproduce the issue using 3.20 :(
HTTrack mirror complete in 1 minutes 57 seconds : 299 links 
scanned, 91 files written (1095008 bytes overall) [4764957 
bytes received at 40726 bytes/sec]
(207 errors, 1 warnings, 1 messages)

Can you try to restart using 'Continue an interrupted 
mirror' ?
