I wanted to spice up my new world where I'm creating a huge minigame, so I added shaders to minecraft. I got myself a barrier block and all of a sudden my game crashes. I load up the same world again later, everything is fine until I give myself a barrier block again because last time it didn't autosave. I decided to wait on the barrier blocks, and wanted to test out the piston minigame I worked hard on. Game crashes again. I can turn off the shaders and everything works perfectly fine.
