My weapon is missing.

I played the map as usual, but when I got a level in the map itself and when I finished it, I took the node and pressed the letter g where I wanted to check what cast speed I have because I'm playing blood mage and the node itself was ca cast speed, however at that moment I saw that my damage was drastically lower than it should be (before:1.3m)(after:400k) where I started to panic and I didn't know what was happening while I I saw that the main weapon is not in my slot, it's a wand that I paid a lot of money for, I want to know what happened there and how it could disappear after only a few minutes of playing the map.
