FIX: compatibility with NPC mods. The ghost look (grey and translucent) was given to every entity built on the game's trader type, so NPCs from other mods such as NPCCore became nearly invisible. Now only the game's own traders look like ghosts. Thanks to Crozekanov for the report.
Also in this file: the 1.6.1 fix - blood rose buds and blooming roses no longer float half a block above the planter.
Nothing else changed. Drop-in over 1.6.0, 1.6.1 or 1.5.x: saves carry over.
