So with the level 74 seeds im getting around 35-40k/hr which seems extremely low(considering you could get 80-110k/hr if you tried hard yourself), none are dying as well(with an exception of a run I did today where it stopped after it using all the water, not sure what caused it but it's not happened again).
another issue I've sometimes encountered is after a 6hr log it stands at the door doing nothing, ill send you a log if this happens again.
I still feel like there's a massive amount of downtime, if possible do you think you could add the 16 back in as an additional option, just to try it out and maybe get it to work better.
Right now the issue that I see is it doesn't really go in lines, and some times tries to double water the fruit,
instead of going
1357
2468
or
1234
5678
it sometimes goes something like this
1,2,6,7
3,4,5,8
I'm not sure why it does this.
when I was doing it manually before this script was around id go
1, 2, 3, 4 - 5, 6, 7, 8
16, 15, 14, 13 - 12, 11, 10, 9
I feel like you've made it efficient enough, but lag spikes could cause 16 not to work, alternatively you could make it so it uses the compost but only does 8 but that's just a thought, not sure how that would turn out.
