Attack move click in 5.19 - broken?

Hi -

I used to have my attack move click bound to the left mouse button when the other day (patch release) it simply stopped functioning correctly. Attack move clicking on the ground now moves you forward as you would if you had issued a regular right click move command - which completely negates the point of using a-move all...

I did the logical thing to do and scrapped my input.ini settings and restored default settings in-game. I now have it on Shift + A, same problem. I have to say this is very troublesome, as someone who plays mainly marksmen and kiting based champions, it's really impacted my gameplay.

I've been doing some searching here and on reddit and it seems that no one else has been reporting this issue so I figured there is a chance the "bug" might be client side.

Would anyone have some insight on this?

Edit:

And for anyone confused by my OP, let me try again to explain this phenomenon:

The reason why I had to change it in the first place was because of the highly frustrating player move function that occurs when you issue attack move click out of range - this is especially annoying when you press a-move by mistake and it moves you forward unexpectedly. Observations: 1. Started happening this patch. 2. ONLY happens when issuing outside of AA range.

Another thing is this makes it almost impossible to rebind attack move click to MB1 because of the major HUD issues you will encounter (e.g. clicking literally anywhere in the shop/minimap/inventory will AUTOWALK you to a random direction.)

I recall reading there being a similar bug a whole season ago, only with the chat back then.

TL;DR: 5.19 introduced a super secret, super small Attack Move Click change that is getting on the nerves of ADC mains. Probably.
