Chaotic long missing runescape bug

I just did my monthly Troll invasion about 30 minutes ago. Then was headed to edgeville to get my runescape equipment for a slayer task (Waterfiends). Went down the fairy ring and noticed my Chaotic Long sword was missing from my equipment tab. I had it while doing Troll Invasion and while at the bank in Edgeville, I didn’t drop it. I had it equipped the entire time.Looked in my bank not there either. Anyone else ever have this problem or available to give feedback?
