To be certain, I retested what I could quickly:
- Slime Crown: Summoned King Slime first time -- also restarted Terraria and generated a new world, but still working first time. This world had the Jungle about 50 blocks to the east of spawn, so that was a nice find! Been a while since I saw such a world!
- Sus. Eye: Summoned EoC first time
- Deer Thing: Summoned Deerclops first time
- Worm Food: Summoned EoW the first time
- Spine: Summoned BoC the first time
- Old Man: Summoned Skeletron the first time
-
Abeemination: Summoned Queen Bee the second time
- Voodoo Doll: Summoned WoF the first time
- Crystal: Summoned Queen Slime the first time
- Mechanical items: Summoned mech bosses the first time
As for why it only seems to affect Queen Bee and Golem, I'm not certain. They're both Jungle bosses, but in that case, I'd expect it might impact Plantera too.
