1. Possible Shen Ult 2. Possible Trundle Pillar and Malphite Ult Interaction

Unfortunately I don't gave any video evidence of these because I don't know how to do that sorry =( The possible Shen ult bug happened to me today. I was Shen and went to ult an ally Azir that was getting blown up by a Leblanc. I must have clicked on him right as he died, because my ult went on the full 170 second cd but no shield appeared and I did not tp to him. I was also not interrupted by anything as I was under turret to avoid that.
The weird trundle pillar - Malphite ult interaction I watched in friend's game about a week ago. The trundle pillared the jungle Malphite as he was ganking, and he must of been spamming R because close to as soon as he could after being knocked up, Malphite ulted and he landed the ult, except neither support nor adc got knocked up. It was right on top of them too so it didn't miss. Anyone else have similar experiences?
