"So when I include screenshots, I get this error message... so: sorry no screenshots for you. Also I shorted the text drastically, I hope I can post now ;v;"
-> the screenshot of the error message was not posted. It said "body: expected text between 1 and 20480 characters". I had 6k chars originally and a few screenshots, but apparently the screenshots cause issues. I'll do it different on the next post - and will not delete text next time.
