Sounds like the timing might be off. It is not uncommon for me to have little loops on top and bottom when I'm doing fsl. I just cut them off. If I think it needs it...like on something that's going to be washed a lot...I put a tiny dab of Fray Check on the backside of where I cut it off.
Changed the needle, it did it again, and there's not any pieces of stuff stuck in the bobbin case, so I packed the thing back up and I'm gonna go to a shop here to get it looked at in the next few days. And specifically tell them to file/polish where that scratch was even if they think nothing's wrong. I printed out the picture I took of it when it happened and pointed an arrow to the scratch, and I circled the spots where the thread broke on my last attempted snowflake, and I'm gonna show them the other two too to show how much it's deciding to make loops. (the english language really is something isn't it...) I don't know how much they'll charge or if they honor the warranty because I don't know if it was the manufacturer one or from the dealer back in Idaho, but they did have a 10% off coupon on their website. At least the last service was free so I only ended up wasting a week of sewing time. I'm just so done with all of this...
:/
I feel for you. The frustration that occurs when things are off is so stressful. Hope you get it worked out soon.
Can one ask how your cat is?
A lot better with the meowing, and the last couple nights hes come to snuggle up next to me like he used to before we moved =^..^=
