One last round of fixes! Thank you so much for the time you have put into this project looking for all of these issues and congratulations on completing the trophy case!
To answer your questions:
1. Why can I sell my old gear (armor) but not my old weapons?
Shooty and Zaat love weapons too much to ever sell them.
2. In a fight, when you hit "x" it takes you to a menu where "Escape" is an option, but it's grayed out. Was running from battles supposed to be a mechanic? (Battles immediately start with options to attack)
Shooty and Zaat are also far to arrogant to ever run from battle, to them it is not an option.
3. What were these boxes for?
Originally in an older build of the game Zaat was not a party member but rather Shootys rival and she would often get ahead of you and take all the good treasure. This map has been in the game since the original demo several years ago and I never took away those chests which were part of that original narrative because I kind of forgot about them, so I guess now they are just a sort of fun piece of legacy content even if they dont make sense in the final games narrative.
