There has been an issue when trying to map my controls for some reason.
I have no idea what causes this, but it has been pretty random for me.
I used to have right ctrl for the secondary key for interaction, but it suddenly stopped working. I mapped it to a different key for the time being. Later I tried to map right ctrl for something else, but it simply failed at registering the key at all.
However, after awhile I tried mapping the primary interaction key to right ctrl and it worked without any problems. Tried to map it as a secondary interaction key but it didn't work again.
Then I just started fiddling around with the key mapping. I found out that the key mapping would just randomly fail for seemingly no reason. Even when the key isn't in use, some keys randomly failed to register when I tried to map them. Wasn't exclusive to the right ctrl key but it also happened to my left ctrl, space bar, and some random letters. I am sure that it isn't something to do with the keys themselves.
