So as from my last post it wasn't shooting and I assumed the problem was Cauldron, now I have removed Cauldron and am now running a vanilla forge server and it seems to only shoot at the pool when I'm NOT close to the spreader.

Botania version: r1.6-184
Forge version: 1.7.10-10.13.3.1388

After posting/recording all that the mana spreader seemed to stop completely, mana is not going anywhere. :D

What version of BM are you running, do you have Whirlwind on your armor? Does that ring dispel projectiles?

Running Blood Magic version 1.7.10-1.3.2-1 and I do not have Whirlwind on my armour as I just installed Blood Magic, but that does make me think about the ring I have which pushes all entities away from me.
Still unexplained is the clogging up of the spreader that I just updated the post with.

The bursts are entities, the spreader is firing, which you can see by the fact that the mana amounts change. It's likely the ring that's pushing the entities away.

Yeah, I turned off my ring and it's working now, but now I have the issue that the spreaders are full and not shooting,

Added 8 more Endoflame's with a Mana Spreader, and it's not shooting either it's stuck with a full internal buffer.

That temporarily fixes the issue, thanks.

Break the spreader and replace it.
