A Few Tahm Bugs [Gameplay]

The first one that I discovered was that when doing the Q W combo on a Heimerdinger turret and then spitting it out the turret gets a period of invincibility, yet continues to shoot. This happened about 5 times in a match and got my ADC killed 2 times. The second has only happened once but was catastrophic for my computer. What happened was that I swallowed the enemy Sona at the same time that my team's Nexus was destroyed. The result was a complete freeze on my computer. I turned it off once and when I turned it back on my cursor was stuck on the League cursor but I was on the desktop, unable to click on anything. It took 2 more restarts to make my computer usable again.

I just wanted to put these out there, Good day all.
