I had a purge just spawn mobs of skeletons inside my base and inside my walls, granted my base is only accessible by elevator and based on a cliff but there is plenty of area around my base for the mobs to spawn.
Question:
How can I make my base safe from purges without them spawning inside my base and foundation blocks.
its designed that way if you don’t have enough foundations on ground level they will spawn inside base very notorious for bases built in water or high up. Always build at least 10 or more foundations ground level and if building in water build a bridge or build something on shoreline that’s where drawbridges come in handy also I have found if you populate the inside of your base with lots of stuff where they cannot spawn in spaces helps as well.
