i made a firework rocket with firewok star that includes feather (for burst effect), glowstone dust (for twinkle effect), red dye, white dye, light blue dye and then made the star but added orange fade. i then made the final product of rockets and set one off to test and watch the display but right after the display was over, i couldnt move. my console then closed the game out soon after. i loaded it back up and tried again. my result repeated so its no fluke. being me i felt the crashing may be an error with the "twinkle" effect when glowstone is used so i loaded in again and re-made my exact fireworks just without glowstone. those worked fine. so i did a test. i made another firework make to test if the glowstone was the cause due to the twinkle effect. i used: glowstone and white dye only for the star, and made the firework rockets. the game froze and crashed again after the display ended. this was all done on Creative so its easy to see for yourselves. please fix this soon. thank you guys for making a great game.
