The problem with the Armour values not being loaded properly after a save is due to two issues in each of the inventory background objects.
1. Under the OnLoad function the 1st line is "saved_data = ' '" which overwrites any saved data before it is applied. Comment out this line by adding "--" to the front or just delete the entire line.
2. Under the OnLoad function, further down, there is a line that reads "buttons.counts = loaded_data". This line is incomplete and needs to have ".saved_counts" added to the end.
Applying the above 2 fixes to all 4 inventory backgrounds allows further saves to be loaded properly.
