So I had this super laggy game (60 ping to 240 ping at times) with Rasmus and I was using my secondary, when I noticed that my secondary was only the recast!!! I could spam it (it used the recast cooldown), but it did not affect anything at all. It didn't fix itself either.
I couldn't use my secondary at all, it didn't give me a speed boost, it didn't swing the scyth, it just took away my secondary and all that happened when I recasted was the animation. I basically had my secondary removed and in it’s place had an animation
I don't know how to replicate the bug, but what I do know is that I was playing on super high ping (200-240, or anything in the reds) (80% sure) when I was using my secondary and recasted simutaneously.
Here are all the clips I have of me using it: https://youtu.be/785dEX6fjZM
