Having trouble with Charlie Fleed's Equipment Upgrade System by Charlie Fleed, Version 1.1 located here: http://save-point.org/thread-2299.html
Ok, let's say I have 2 Bronze armors, and 1 Poison DEF enhancement (protects against poisons). I call the script, put the Poison DEF enhancement in 1 of the armors, and then leave the Enhancing screen. Then I equip both of the armors on 2 different characters and go fight a giant nasty venom-spitting snake monster. Both of the armors all of a sudden protect against poison.
While using Stormtronics CMS I noticed that when I had two Bronze Armors and 1 had the Poison DEF crystal in it, both of the armors had a poison state defense icon. Not good. When I took out the Poison DEF crystal, I went to the equip screen and both armors still had the poison state defense icon, and neither had the crystal 'installed.' So I copied the game over and deleted all scripts except Fleed's. Blargh, there's that ugly equip screen, but it now shows how many slots the armor/weapon has in the description (doesn't do that in Stormtronics, but I can live without), and, after placing the Poison DEF crystal in one of the armors, the armor with the crystal showed the crystal in the slot, the other did not. Awesome! So I equipped both armors on 2 different characters and went off to fight that snake monster again. Both were still protected against poison. I went like 40 rounds against the snake monster, each round it spat poison, each round the poison only affected the 2 characters not wearing the Bronze Armor.
It seems it is not creating a new version of the Bronze armor with the Poison DEF like it's supposed to, and figures both armors have the new state defense. In fact, if I had 30 Bronze Armors and put 1 Poison DEF crystal in just one of them, all of them become protected against poison.
