User blog:Neodude/Need Help with King Slime Summoning Glitch

Okay, I have decided I want to get my hands on the full ninja set. Instead of sitting at the edge of the world with a water candle, I have crafted 5 or 6 King slime summoning things. I used one and it worked fine, teh king slime showed up and I beat him. However, on the second spawn, it said he had arrived, adn yet I sat around for 20 minutes wating, and he didn't show up, I dug around to see if any caves where nearby and there were none, jsut a large flat area. After a while the boss music stopped. I just tried again thinking if I reloaded Terraria it would work...but same thing. An ideas on what is gonig on? I really don't want to lose any more king slime summons.
