K-pop group leader RM aka Kim Nam-Joon, posted on social media that he deleted an unreleased track by mistake while formatting his computer system. RM posted on Weverse and said “I did cleaning wrong today. So the file I was working on, all the audios got deleted. Just mental breakdown in itself. Still, I tried having strength. I was almost done with it. I am sure this is the worst day of this year. I'm going to record it as a moment since I'm sad.”

Since Army was all worried and sent RM methods to recover the files, he later posted, "Oh I thought you guys would worry. It's just one song. The other songs were safely kept by others but this had over 60 tracks that I recorded so I don't have the courage to re-do everything. I'll let you guys hear it one day. Everyone, be careful when using a cleaning program."
