You need to manually drop 0/2 bombs in order to craft more. Totally absurd behaviour.

Also if you have a fast hard drive (i.e. raid0 ssd or pcie ssd), you have to wait all the "loading" video (and hear it) no matter the game was loaded several seconds ago.

I agree loading screens need to be changed. It's a well documented concern. I got to Skellige Islands and immediately took a break, before exploring. Come back, and the loading screen completely gives away the plot. :(

As mentioned above, bombs, potions etc. are working as intended.

Also, you can ( partially ) skip the loading screen story sequences. I have the game on an SSD, so a few seconds into the story sequence, as soon as all the data is ready, I can press a button ( X on the 360 controller, in my case ) and don't have to watch the whole sequence.

Here, have this: http://www.nexusmods.com/witcher3/mods/66/? With this mod you can disable those loading videos you seem to hate so much.
