Shop Glitch
Observation
After changing my keybindings mid-game, I lost the ability to purchase items in the in-game shop by right-clicking on item icons. This applied to item icons in all sub-windows within the shop.
Workaround
It was still possible to purchase items by double-clicking on item icons or selecting an item and clicking the "Buy" button. Furthermore, the bug seems to resolve itself upon loading into a new game.
Recreation
Binding a new key in relation to [MB2] (Mouse Button 2 - "right-cilck" will cause the bug to occur. Various actions that cause the bug to occur are as follows:
-Changing (adding, removing, or replacing) an alternate key for any command where [MB2] is the other key. (This works with [MB2] as both the primary and secondary key.) -Changing the key for any command to [MB2], be it from an existing key or from a previously-unused key spot in a command. -Doing any of the above actions with [Shift][MB2] or [Ctrl][MB2].
The following will NOT cause the bug to occur:
-Changing any keybindings around other keys, most notably [MB1], [MB3], and [Alt][MB2] (unless an applicable [MB2] variant is involved in the change). -Unbinding [MB2] (or applicable variant) from a command or changing it to another key (that is not an affected [MB2] variant).
Other Notes -This bug was observed on patch 6.1 -This bug applies to all maps and versions of the game (Summoner's Rift, The Twisted Treeline, The Crystal Scar, and Howling Abyss). +1
