1st: Kitchen Bots are a part of Robots++, but nonetheless: You do know that a kitchen bot is for tending the kitchen? If you want it to farm, you should get a farming bot :)

Same here. They simply won't harvest anything. They plant, though.
@Haplo Kitchen bots are supposed to be improved version of gardener bots which by the way, don't harvest either. ;)

Fixed on github. Waiting for upload.
@Aureus i fixed it, you can download form github or wait for upload to workshop

I have the same issue. I added my own bots and until 1.4 they worked. Now I have to use designators like "harvest fully grown" or else to make them harvest.
I also tried by using robots++ to fix it, but without success. Robot worktab support fixes this and other issues, but takes firefighting away from my bots ... yes life with MOD's will never be easy ;)
@VeteranXT wahts the fix? DO I need to lern coding for it?

90% of time is mod conflig? like designators ? Is this part of some other mod or vanilla?

I mean the options provided by "allow tool". "Harvest ripe plants" is it called. If I mark some plants with "harvest now" (sorry I do not play in english language) or the other the bots immediately start harvesting, but ignore the non market fully grown plants.
I went trough a lot of mods, changing settings, disableing/enabling ... but with "robot work tab" they show normal behaviour (except for firefighting, what they are supposed to and do without "robot work tab").

Well they do without work tab. I dont have any issues with it. I dont use Allow tool so idk what to patch or fix.

I tried without it and without other MODs as well. Key problem is that they do not harfest unless I set a plant to be harvested. With the worktab mod active they do ... robots++ behaved the same way. It annoys me that I can't figure it out. Nonetheless thank you for your time and patience.

Well what i know is that they only harvest 100% crops. Unless asked to harvest beforehand.

Yes, you are right. Problem is that they don't do this and that I have to additionally mark the plants to be harvested. It seems they do not recognise fully grown plants as fully grown.
I also got other little things with miners just occasionally going to quarry or haulers ignoring some tasks. Before 1.4 I was always able to find what I messed up, but know it's just weard.
Maybe CE, fluffy work tab, allow tool, ... what ever ... spits in my soup ... No need for you to waste
your time ;)

Well 1.4 brings many changes. And many mods do break alot of stuff. There is some mods that will prevent any harvest. Fluffy work tab should be fine.
Give them time, they maybe have something else to do that is higher priority. If they just refuse most likely is mod incompatibility. What i can do i just look for mods/logs and tell you what might be causing this. Last time robots didn't even do operations, i managed to fix this, and now every bot does it job. Some mods need more patches on my end.

Thank you VeteranXT. But first I have to nail down the MOD that causes the issue. I read about your fix for robot surgeons. Good job!

Edit: I did a bit of testing and was very surpised. I build a test greenhouse with normal ground and "simple soil" rich soil. Placed bots next to it and, surprise they did like they should. Then I placed mountain roof above it. First it seems to work, but after I let them do work unrestricted, the began refusing to harvest again. I think I have to go further with the mountain roof theory.

Edit 2: It seems like the count of growing zones is the culprit. As soon as I removed zones (flower boxes for example) the started in a couple of zones harvesting.
I recognised it by placing two identical greenhouses next to each other with fresh bots and most other zones (at this time I didn't had the flower boxes in mind) deleted. Surprisingly the worked great in one of the two zones and after deleting the working one, they started in the neglected one.

Bad news. This also doesn't seem to be the culprit.

It seems like total random bug.... ¯\_(ツ)_/¯
What you want me to do....? Cuz i have no idea what to fix.

And people please post this on Misc.Robots++. Keep haplos mod clean. That is what he would ask.
