The queen bee isnt only spawning during frost moon (although it seems more common to happen then) but she is also spawning randomly during non events aka normal play...idk if it may be an issue with the spawn ai but that is what it seems to be cause she spawns just like the eye of cthulu does on random nights. But the queen bee does seem to be spawning fairly frequently compared to other bosses such as the eye of cthulu and slime king. I am currently testing a theory i have (making a new map killing all bosses and defeating all events and destroying all larvae) to see if it is an issue with older maps or just a mixup in the coding. Anyone else willing to help me in my venture i woudld be very grateful if you could post your findings so as we can nail down what exactly is causing it. (If it hasn't been determined already)
Edit: Btw my arena is DicemanX's original Horseman's blade arena in a snow biome that i recreated on the xbox by hand.
