Bard Stun and Tunnel numerous bugs

Hello! I am writing here hoping that you (RIOT) review these bugs that I've experienced over the past few weeks. I have started playing Bard really often and the more i played with him the more i noticed weird and strange things happen. First of all is the fact that sometimes mid-wall (while in the Magical Journey his E ability) i get hit a.k.a the projectile hits me after i have entered it. Another common bug is the Q (Cosmic binding) where the projectile would hit and contunie after the hit its ordinate (as it is supposed to do) but then even when it comes to contact with a wall ( this has happened to me at least 10 times for just 2-3 weeks of gameplay and only when the projectile hits a wall!) it would ignore the stun state and the enemy champion would do an attack or cast an ability regardles of the fact that the stun should interrupt it. I am completely sure it hits a wall because I've seen it and a few of the times it occured the situation was whereas the enemy would follow me in the magical journey and thus behind him there is a wall so stun should be imminent. Hope you review these bugs!
