I was doing an attack for artfight and I was using kleki. It gave me a warning that i should save just in case. I ignored because I was like it won't be long until I'm finished. Welp I was wrong! I accidentally hit the kleki home page and it opens a new tab. I'm like ah sh*t so I close that tab and click back to the piece I'm working on. THE FREAKING TAB RELOADED and I lost what I was working on! T^T It looked really good too! I was really happy with the line art and everything about the piece and now its gone!😭
