Hey this should be fixed in 0.2.5
No worries for the spam, I like that there is traffic on my page!
The problem was that I did actually change the output slot to 1 since it is a smaller machine, so the mod adding the seed to the plants expected result, didn't have output space in the tower.
It works in your save instantly.
I see that some mods also override the surface condition, the Zen-tower was designed only for Nauvis since it would be just massively more overpowered on Gleba than normal Agricultural towers. But the Mk-2 should be overpowered anyway so have a blast with it on other surfaces ;)
Feel free to write if you encounter anything, or have feedback.
Cheers!
