The "How to report a bug or crash" thread tells us:
"Please pack it all together in a .rar or .zip file (using Winrar or 7-zip for example) and attach it to your post. If it's too big, you may use an external file host such as wetransfer or dropbox."
But when trying to attach a .rar file to the post the site says:
"Invalid file type. Allowed types are: .png, .jpg, .bmp, .pdf, .doc, .gif, .jpeg"
Please allow .rar & .zip files as this will increase the quality of data you will receive
