Ok, so, since I finished the blacksmith mission yesterday, I managed to create some iron plates. So I tried to upgrade the Rouge's armor that technically should have 2 slots. Even though strangely the game had removed the slots. Anyway, even though the slots were not visible, it still made me apply the two iron plates per piece so 4 pieces with (+2).
Since it was late, I saved, closed the game and turned off the PC to go to sleep.
A few minutes ago i return at home, I started the PC and the game. And the upgrades on the Rouge's armor remained present. It still gives me (+2). So everything should be ok. Even if I still don't understand, why, the slots disappear after closing the game. But oh well, the important thing is that they can be upgraded and the upgrade is not removed from the game, with a possible restart.
Also thanks for the link
RPGM save editor. I already had an old version of the save editor. But strangely the version I had, told me that I could not use it. Because of some limitations that I do not understand. Now however the version I downloaded from you link, 0.96, opens without any problem and lets me add material and other things.
Sorry to ask, can you help me with this other problem too? In the current save I'm using v0.6.0.0c, after training with Lyvia, the protagonist has unlocked the weapon mastery talent. But in my old save v0.5.0.5, where I'm much further ahead in terms of plot and missions, I noticed that I don't have the weapon mastery talent, but I finished training with Lyvia a long time ago. I assume it's a talent added only recently. And now I wonder how to unlock it, even in the old version. Someone suggested me to fiddle with the save editing. But I don't even know where to start. I also tried to use the RPGM save editor, but among the switches and variables I didn't find anything called weapon mastery. Either it's called differently, or it's not possible to do it from there. Do you know how I can solve this?
Thanks in advance
