enum stops at one point and wont continue

[dpalavra]

amass enum -d example.com -o example.txt command is ran with the domain of my input but it stops at one point. I let it run over night and its still stopped until I terminate the process.

Then I ran :
amass enum -active -log amass.log -d example.com -o example.txt

with tail -f amass.log gives the last lines of the log, nothing else is produced after that:

23:03:11.543708 ShadowServer: asn callback: :56: cannot perform concat operation between string and nil
stack traceback:
:56: in function 'origin'
:26: in main chunk
[G]: ?
23:03:32.049190 TeamCymru: failed to resolve the TXT record for ASxxxx.asn.cymru.com: the query was unsuccessful for ASxxxx.asn.cymru.com

Is there a way to force amass to continue if it encounters an error of any kind? After few tries or 30 secs of error not resolving, just to continue?

Thanks

Mine is frozen as well, just stuck.
