Many Keybinds Ceased To Work After Dungeon

This has never happened prior to 6.01 so ...

... on exiting Vanaspati many keybinds not associated with hotbar buttons ceased to work, ie. 'M' no longer brought up the map, 'P' no longer brought up the Skill dialog. All binds in the Shortcut keybind tab were affected, none in the Hotbar tab were affected, no idea about other tabs.

I could open the map using the menu system as well as the Map tab in Journal entries.

ESC no longer brought up the system menu, but that was also still available from the menu buttons.

Given the horrendous queue times I wasn't going to log out and back in to prove the probability it was a glitch, possibly exiting the dungeon or the cutscene (in which I presume the client disables most keybinds).

Note that the Keybind dialog was normal, 'M', 'P', etc. were all present an correct and if I tried to re-map one of them to another key I got the expected "this is already mapped to <such-and-such>".

I'm expecting things to be back to normal when I restart.

To confirm the expected, on reloading the game the keys were working just fine.

I posted this simply to record the fact it happened, clearly there's little for anyone to go on but if more people than just me report it the clearly there's a problem in need of fixing as it hinders actually interacting with the game very tedious for many things.
