I have the crimson (NOT corruption), killed the WoF, but i only get Demon Altars. They have the graphics of Crimson Altars, but when i mouse over them it says: Demon Altar. I've destroyed a bunch of these crimson looking Demon Altars and all i get is Palladium / Adamantite / Orichalum. Why wont the titanium spawn?
The tool-tip for Crimson Altars is Demon Altar. This is a bug in the game. Both Demon Altars and Crimson Altars can spawn the alternative ores. The one you get is random and not linked to the crimson/corruption of the world. Your world gets one ore from each tier by random.
Hardmode Tier 1 | Cobalt OR Palladium Hardmode Tier 2 | Mythril OR Orichalcum Hardmode Tier 3 | Adamantite OR Titanium
