I was fighting the solar pillar with the Meowmere sword, and I was doing really well, I had actually just killed it, when I died. Now, dying's not a huge deal to me, especially considering I die all the time, but I happened to look at the death message and it said:
Darth McButtkix's vital organs were ruptured by Meowmere.
How did that happen? I thought my nyan cat minions were supposed to hurt my enemies, not me. In the past, I could run into them all I wanted without getting hurt, but for whatever reason, this time they killed me. Is this a bug? Or is there a Meowmere mechanic that I'm missing?
Picture for proof:
