      Description

      Clientbound play packet 0x0C (Boss Bar) uses the same byte value ('2') for two different booleans.

          private void setFlags(final int flags) {
              this.darkenSky = (flags & 1) > 0;
              this.playEndBossMusic = (flags & 2) > 0;
              this.createFog = (flags & 2) > 0;
          }
      
          private int getFlags() {
              int i = 0;
              if (this.darkenSky) {
                  i |= 1;
              }
              if (this.playEndBossMusic) {
                  i |= 2;
              }
              if (this.createFog) {
                  i |= 2;
              }
              return i;
          }
