1/ edit: ok so i tested everything and it seem all characters limits break 4 is working when learning it from the item, only dyne dont work, after many test there is no way he can learn the limit 4 with the catastrophe item, there is no reason for that, and this make me mad, since he is the only character with this problem i just give his catastrophe limit break at lvl 3, to summarize, when you 'll use the limit break lvl 3 you will use catastrophe ( L4) , thats the only way, but now to gain his lvl 3 limit break it will require 300 kills instead of 250, and the catastrophe item is now unusable (since he is useless), so the problem is solved.
2/ i used the chocobo for avoid midgar zolom fight in cd1 and i had no problem, this problem occur all time? or only with certain type of chocobo? ( i had this problem with elena world map model thats why i finally didnt put her in the mod, but it seem sephiroth and rufus model was ok in world map) , anyway there is nothing i can do for this, if its really annoying for you , the only way would be to restore the original cloud's worldmap model ( WM0.BSZ)
3/ its not a bug i did this on purpose, since there is dyne, a limit break including diamond weapon and ruby weapon, i made the contain materia using these characters spell animations
Freeze is coktail molotov
break is s-mines
tornado is ruby ray
flare is diamond flash
These spells are strongers too so care when a behemoth use " flare" (diamond flash) this will hurt a lot
I will upload dayne's new limits break with the last upload of the mod, since the game is soon 100% tested.
