Yes. When I tried again today, was on de_dust2 T spawn going towards long A, and I was able to actually cast it there in the open. I saw the red beacon indicating that I was casting and the message stating I would be frozen for 10 seconds. Well, I counted to 10 and then hit my +ultimate button again, nothing. I hit +ability1 thinking it'd show something and nothing. After I decided to move, is when I crashed.
Came back on de_piranesi and crashed multiple times trying to replicate what I did in CT spawn.
I'll have a 2nd person later today to mess with it for a bit.
