I tried to edit the Shivgoroth Form's transformation into a new custom tile, but it didn't quite work out as I was expecting...
 
 I mean, I added a new .png file to the npc image folder and edited the talent timed effect to show the new tile, but it just made my character invisible. I did double check if the file name or file size were wrong btw.
Then, I returned everything back to the original state and decided to purely edit the Shivgoroth's image file itself... by just pasting the new sprite over it...
 .
.The new one fits the 64x128 size, has a similar shape as the original one and I haven't touched the file name or file size or the skill algorithm. Yet, my character goes into Elemental of Stealth mode again.
So... What's the deal?
Happy Christmas btw
