I've just had a dialogue interaction with an NPC called Chris in the mission where you launch those crazy ghouls in their rockets. While clicking on some of the dialogue responses, there were multiple occasions where I couldn't read his texr because it just flashed really quickly as though I was madly clicking my mouse.

Also, when on any of the crafting screens, if I move my mouse cursor over to the list on the right that shows the recipe ingredients, I hear a constant buzzing stream of mouse clicking.

Anyone else seen this weird behaviour?

The buzzing mouseclick sounds are annoying indeed. I also noticed that you can't see in the list on the left which item you selected. You only see an icon...

This problem, and the hardcoded 2-key, makes me think some parts of the game were rushed and they didn't have the time to polish these 'temporary' placeholder features.
