Greetings SentinelCraft staff members. This is SuperSonic14045 speaking.
For some reason, barrier blocks seem to be present in the Biomes Mob Arena near the sand area. This is most easily noticeable when standing at the respective corner and slightly looking up and left. Attached is a screenshot with some arrows shot at the barrier blocks evidencing this.
The reason I have reported this is because these blocks may sometimes prevent long-distance bow shots, which may disrupt gameplay. Also, I believe this was not intentional.
