More info: Singleplayer superflat world, the command blocks were working, then i switched to survival to test a spawnpoint and typed “/kill” into chat. Earlier, if i typed “/kill @p” into chat while in creative mode, it would say “No targets matched selector.” After I died, I switched back to creative and the command blocks just stopped working.
Because this might’ve been the same thing reproduced by mistake?
Was it like this?
I recently restarted the app and they worked again.
