I've started a new world with an existing character to start playing 1.3. I'd then killed the WoF and entered hardmode, I was planning to ace through this and quickly get to the Moon Lord boss. But I have to first get pass the three mechanical bosses and so on... In order to do that, I have to find the souls (Soul of Night, Soul of Light, etc.) to craft and summon them. I went down the corruption underground (Both Hallow and Corruption). And I've been killing the monsters and other AIs for over an hour, but none of them dropped any Souls. Could this be a bug or am I missing a step?? P.S. Guide is also not spawning after I sacrificed him to summon WoF. AI spawn rate seems a bit low as well, like the Wyvern barely spawns.
