yah, nothing has changed in my code for months so... And never had a problem b4... But I have seen Steem API change sudden and random in the past which will cause undesired effects in scripts. Happened a while back with the user list checking and saving to json functions... the timing got messed up and it required a timer function to slow the json write down or it wouldn't save... stupid...
Worst comes to worst I will simply disable the comment function. then it will just post that unable to resteem thing in my trans log...
Hopefully it doesn't come to that.
