Hi! I'm getting critical error when i try to load the game with my edited L2UI_CH3.utx file. The steps i do to create my file are the following: 1. I use l2decrypt to decrypt my .utx 2. I open it in unreal 3. I add the icons i want and compress them in DXT3 4. Then i encrypt it back with l2encdec with 121 encryption I'm not sure but i think i do things as many guides here suggested but i still get critical error on game start so can someone tell what i do wrong here? Edit: just to clarify things more i only get critical error when i try to edit the existing L2UI_CH3 file...If i create a new utx i have no issues.
