Eyeplant-spawning seems to be bugged (or I'm misunderstanding the mechanics), exhibited in a fight with bee queen. After 1-2 days of bee queen's presence, the eyeplants within bee queen's range will stop spawning. After a server restart in this situation, the eyeplants will start spawning (1 by 1) immediately after starting the sim, but the spawn pattern is erratic - the radius of the spawn ring is visibly greater, and large areas within it still don't have any eyeplants (though this may be because the enlarged radius now causes in-fighting between eyeplants from different lureplants).
Also replicated with almost no mods (only "Fix for Too many items"). Game save before replication attached.
Place several fleshy bulbs in a patter of 7x7 tiles near honey patch Lure bee queen and grumble bees into eyeplants. Observe as eyeplants stop spawning, even as the bulb still hangs the lure.
