I think my reasoning was that there’s no reason to actually sync an attached object since the parent object being synced should be enough to make sure the position is the same everywhere. If it works for you with that commented out though then I say go for it. I’d have to search through past issues to really know what inspired that change, but I know it fixed an attachment issue for someone. I’ll add a task to my list to look in to it more and see if I can rework it somehow to fix your issue without breaking stuff for others. Not super high priority though since it seems like you’ve got it working anyway
