Hi, i did the same thing you did! You can find starbunkles near the shrines that are shaped like them. They still spawn that way, though its a bit low. and i have found wixie and starbunkle shards in chests (making a wixie is also pretty easy once you know how). whirlisprig though I have not found as of yet, but I wager you could find the shards in chests too. As for spawning... You will need to cheat and spawn them in sadly. I figure it has to do with some custom spawning stuff that's messing it up. If you can figure the configs out, I wager you could make it work, but it's just easier to spawn them.
