Happened to me too. Started a world on Java 1.14 and updated to 1.14.3. I believe the chunk the fortress is in generated in 1.14.3 but I’m not sure. I never got any spawns even after toggling the difficulty but the /summon command still works and the mobs don’t despawn. There are also no spawners in the fortress but that could just be seed related. I am running Optifine with shaders but no mods.
