It’s been a while and I wasn’t available, but I can answer. The characters other than Twinblast are being used as you suggested, so there’s no crash in the engine, at least for now. The other character doesn’t really matter. I may have extended this topic a bit too much, but my main goal was to learn the problem and its solution. I wanted to have the problem and its solution in my pocket in case I experience a similar problem on the projects I work on in the future. Thank you for your information and guidance, good work.
