sorry, but I should have made it clearer... the console window has many tabs, and that tab you put there seems to be the "elements" tab. The one I need is the "console" tab.
that said, I think I did find the cause of the problem through Yanfly's error message, seems like I forgot to initialize the buffs of the new parameters with the new characters, somehow in my tests it skipped any checks without it being initialized before being checked... but that's ok, that's what tests are for, I think it may be fixed now.
Would you mind testing for me? A new save file may be needed for that, sorry.
