I made and maxed out all of the mystical agriculture essence bees because I wanted to mass produce essence, but they bees do not pollinate from the essence blocks as said in JEI. It is expected that they produce their respective combs.

Which version are you on and can you please show a screenshot of your setup

productivebees-1.20.1-12.1.3, Forge 1.20.1 - 47.1.0, minecraft 1.20.1, MysticalAgradditions-1.20.1-7.0.0

They are all metaturnial, and they don't seem to recognize their polination block and fly arround ignoring the feeding slab when simulation upgrade is out. Same with the blocks instead of feeding slab. Prosperity and soulium work fine along with all the other bees i have.

move the slabs down 1 block into the flow

that works! but why are they different? i moved it down and the immediantly pollinated and produced combs but why are they different? anyway thx.

That’s how the hives are coded, the flowering block has to be in a specific place for simulated hives.

I now realize why I was confused. I am going to use this comment to explain to anyone else who might be confused in the same way as I was.

All of my other hives were designed without the simulation upgrade in mind.

But when it started getting laggy, I put in the simulation upgrade for some of them and added a block (thinking it was nessesary)

(Notice how I don't remove the floor)
Then when I put in the mystical bees, their setup looked like this.

I thought that the mystical bees were different because I didn't realize all the others were using the floor that I didn't remove instead of the block I added for the upgrade.

Thank you for the help.
