I encountered a bug on version 2.2.2 mac version (i havnt tested the others/ cant) in which equipped weapons do not get used nor do they affect the stats of the player. ive tried completely removing all save files including the persistent file, unequipping the weapon, unequiping and reequiping, unequiping saving loading, unequiping saving loading and requiping, all of which do not result in the stats of the weapon being applied.
