Alright, I've been playing the 3DS version for a while now, and I have some bugs to report:
-Spawning issues
-Illuminant slimes spawn on the surface
-Giant tortoises and Angry trappers don't spawn underground
-Waterleaf does not spawn in deserts
-Grounded invasion monsters will, mostly, despawn instantly (i.e during pirate invasion, mostly parrots will spawn)
-Not sure if a bug or not, but worlds will spawn with a desert or a snow biome, but they will never be together in the same world
-Meteor heads don't spawn (?)
-Fishing issues
-There is a very small window of opportunity to catch fish
-Quest fish are incredibly rare
-Quest fish do not show up in their correct rarity
-Mechanic doesn't sell her respective fishing rod
-Other issues
-Not really a bug, but the Giant Harpy Feather is spelled as "Giant Harpey Feather"
-Souls of Light and Night can be obtained on the surface, but they are much rarer
-Not sure if they are implemented or not, but the Eye of Cthulhu won't drop crimson grass seeds
-The spread of the Hallow, Corruption and Chlorophyte ore is incredibly slow
-As ridiculous as it sounds, ducks are spontaneously appearing on the ocean surface!
-Some rare items seem to be not as rare, while common items are rare (i.e I have gotten 9 slime staffs in my world so far, but only get 1 lens in a single night)
-When talking to the angler, the image of the respective quest fish or tips on where to catch it will not appear
-Not sure if a bug or not, but the mechanic sells 1, 3 and 5 second timers
-Framerate issues
-Scourge of the Corruptor destroys the frames when spammed
-Flame traps when used with spiky ball traps destroys the frames when hooked up to a 1 second timer
-The final wave of the pumpkin moon destroys the frames, even more so if you used the flame/spiky ball traps to get that far
-The Golem
-The Lihzahrd Altar will never spawn in the center of the main room (mine actually spawned at the entrance of the temple!)
-Sometimes when spawning in the Golem, his fists will attack at the speed and deal damage as if the head was defeated (really fast speed and really high damage)
