dash over wall not working

Hey,

as a true lol player i thought i might share my information. i went online today and went playing 3 games with my friends. 1 game of ekko. 1 game of kha'zix and 1 game of graves.

game 1 Ekko: as I gank toplane i mostly dash over the wall on top behind the tri-bush. but this time as i dashed i got stuck in the wall and got teleported back to the place where i started my dash. nothing bad happened after so its not really bad... as i use no screen recorder and cant find my game back ill post a link of a Nighbtlue3 vid where in the intro he has the same problem at about the same location. link: https://youtu.be/BTre2RWgLJ0

game 2 Kha'zix:

as i got lvl 4 i got my e already ofc. so after doing scuddle i decide i am going to invade enemys red buff. so i walk to the bush behind dragon pit and jump over the wall, but again instead of jumping over it i get teleported back, again not with major things to happen.

Game 3 Graves:

as i approach baron ito ward it the enemy team spots me, i decide walking to the back of my blue buff was the best chance of me getting away and i flash towards my blue. once i am at my blue i dash over the wall from the back of blue but once again i get teleported back, this time into the enemy team. because of this i died and my team (consisting of friends) die in the last team fight and we lose a game that we could have simply won.

conlusion:

can u guys as Riot games summon the Rito gods to exterminate this from happening? or wont i ever be able to das through or over walls again?
