Tree Planter - refuses to plant certain place

Planter refuses to plant on the top left. I got no idea why.
I manually drove the planter there, it returned to the forestry tower. I tried removing the pipe (height 5 fits anyway). I removed and replaced the designations.
Mysteriously, it did plant one tree, just at the pipeline. Looks like it reached it from the right of the pipeline. There is a large square boundary (thick black line, what are they called?) just at the water pipe. Maybe that matters. Though I do not have this issue elsewhere, see bottom left, also a different large square.

I added another forestry tower, reassigned the harvester. It instantly started planting.
So the designation is fine.

Ran into the same / a similar issue with a track being a "magical barrier" that planters didn't want to pass: https://discord.com/channels/803508556325584926/803519296864518184/1467238902053077293

Tried assigning a new planter, but it would just idle at the tower.

Redid the designations too and that initially didn't seem to help either, but then a while after a reload I noticed they finally had started planting.

Maybe it's a matter of a tree planting designation exsisting (& it's ready for planting),
such that it's located in a place that can't be reached by the planter,
within this "bigger chunk" (the black, thick-line outlined area)?

I know that it's possible for that to be a problem.
Kind-of how sometmes trucks could have gotten stuck at one point
(or at least I'm pretty sure that was a problem at one point in the past).

Maybe try removing all designations with any slope on them and see if it can find a path to the flat ones. I think its possible that vehicles try to path to impossible to reach tiles and then give up.

I had the same issue here (https://discordapp.com/channels/803508556325584926/803519296864518184/1470578512594469067) and this did in fact fix it.

Sorry, it was this one that fixed it

Seems like the reason are the "Forestry Designation´s" in the red "no path area".
I tried serval option with your save.
If you place the forestry area at your unplanted space the planter start working. that was my first attemp

So i though make it bigger. But than the planter stopped working.

So i tried this one and it worked.

The last picture has no unreachable designation inside the square.

So i made the forestry area bigger again and deleted some unreachable forestry designations and it worked.

Good job analyzing! Now we still need some developer to fix this ...

Yeah, I keep falling into this trap. When space is tight, I use slopes and other ”garbage” terrain for forestry, but when there are too many unreachable tiles in the designation, planters can get stuck idling. It’s a chore to flip between navigation overlay and the designation and manually remove all unreachable tiles. Something that the game should be able to handle.

If you pin the planter/harvester window you can kinda see both the nav overlay and designations at the same time. The green on green doesn't help though..

still tedious
