Forgot to report something I totally forgot when I played Cyro.
Sometimes the Ice Wall was cast’ed but didn’t show up on screen but the animation for it was done and you also saw a shining blue glow, that happens when you cast it (these small ice fragments).
I tested it for several hours, in town, casting Ice Wall on places no one would normally do, I moved players on top of it, pushed them down and even then that little Bug did happen, with the Ice Wall just not appearing but it was on cool down.
And before people come with “it was your network” a friend of mine (played same route, just diff. skill) had the same problem and we both have 50/10 Mbit/s - Down/Up.
We tried to find the reason for this, but really didn’t. Since the place was not at fault here. That little “bug” did happen on the same place where the cast worked before.
