I am using lightburn on a Mac. And since after this morning I have noticed that the shapes are not closed anymore. So, I am unable to cut them because they give me that the shapes are open. This is very strange because I was using an online box generator to get a burn test and it is an automated generator and has never given me that error before. Just to double check, I opened the previously downloaded file that had cut perfectly without giving the shapes open error and it is giving the same error.
Did I change some setting in the software when I was working on image tracing this morning? This is frustrating. Thanks!
