[Bug] 0.21141 Situation where input focus is not transferred back to the game from the menu

[HofNerd]

I found something interesting today, have a look:

When I go to the menu, click reload last save and then click cancel the game resumes but without responding to most of the input. (Clicking on surfaces, WASD keys for camera movement, etc.)
(I am guessing it has something to do with focus traversal? I honestly have no clue, my programming is very limited but it is the only thing I can think of.)

I may not have been specific enough. What happens is, the game does not respond to certain input in a way it is supposed to after the following steps:
Go to formicarium,
Click reload last save,
Click cancel.
