Okay, so, bug report. All Thorium NPCs (both in single and multiplayer) always move towards the left and stay there. They don't move around. The only exception to this is the Desert Traveler. He seems to be moving around just fine. I have the Druid, Diverman, Confused Zombie, Cook and Desert Traveler moved in. The Desert Traveler was the last one to move in.
I don't know if anyone else it experiencing this, but if they are, would be nice to get some confirmation. At first I thought it was only the NPCs that were made before the update, but seeing as the Diverman is affected as well, this leads me to believe there's something wrong with all of them except the Desert Traveler. Also, were the Firestorm Boots intended to make you immune to lava? As long as they are on, I can literally go under lava and stay there as if I was wearing the Obsidian Set or an Obsidian Skin potion forever. If this is working as intended, cool. If not, well, bug report. lol
