All the bugs are related to the inventory and bartering.
1. The two white arrows in the inventory screen that allow you to shift between characters. Sometimes they're bright and work. Sometimes they're a little dim and don't work.
2. When I'm in the bartering screen, it seems like I could shift between characters (using the two white arrows at the top) and see whether the equipment the NPC is better for certain characters and whether they can be used. But now, the stats in the NPC equipment only relate to the character who ininiated the conversation and bartering section.
3. I put a bunch of stuff in backpacks. Sometimes I put some of the backpacks in the action bar. Sometimes I just leave in the inventory grid. But X number of minutes later, everything that was in the backpacks is now separate and in the inventory grid. The backpacks are empty.
Is this common? Was my save corrupted? Will it help if I start over? Is there patch that fixes these things? Or should I give up and just go and play Wasteland 2? And maybe go back to Divinity when they release a patch that fixes these things?
