Tower bug

I have noticed lately that there seems to be a small, but very annoying bug with the towers. So every now and then we get knocked into towers, walk around them, flash next to them etc. but what the bug is, is that you can get "caught" on the tower. for example i will be walking past a tower base, as in the bottom of the tower, and if i get to close i will get stuck where i am and can not physically move forward. it's not a major thing to worry about unless you are diving or being dove, but it stops you and it takes a few seconds for you to get unstuck. I'm sorry i can't be more helpful about this or provide any evidence to support it. honestly it is only an annoyance and nothing like a major bug like the Trynd - Xerath Q bug. but i just thought it worth noting in case it escalates or causes other bugs. thank you for your time ^_^
