I can reproduce this issue. Chests' textures are broken. I attached the crash report.
Fixed this and all related issues by reinstalling the snapshot.
@[Mod] tryashtar No, it's set to Needs Redstone.
@Jack Donegan As I have learned, chain command blocks are executed only when they receive information from command block behind them. This chain is somehow started by repeating command block that isn't powered. I don't think this is an intended behavior.
@Dhranios Thanks for your clarification. I don't understand Minecraft's technical side so well as you. It was my first time trying out that command, I didn't expect a crash.
