Hello I get this error when trying to start the game with this mod active,

Failed to load mods: robot_tree_farm_update/data-final-fixes.lua:772: attempt to index local 'stump' (a nil value)

Update to previous comment,

I'm able to start the game with this mod with Space Age disabled.
Is this mod not compatible with Space Age or am I facing another bug in my installation?

Space Age compatibility has not been tested.
This mod was created when there was no way to plant trees.
Given that SA offers it own seeds and method of planting and growing trees, I assume there would be little interest for this mod. Also compatibility problems could arise.
Anyway, the problem is probably due to some new species of "trees" that SA introduces, which when mined, leave a fire or explosion instead of a stump.
I could possibly provide a quick fix for this but I am not sure that it would suffice for full compatibility with SA.

Ah okay, thank you for replying.
The reason I want to use this mod in SA as well is because it allows the seeds to be placed by bots and a lot tighter as well then the SA ones.
Additionally I prefer some trees over the standard one you get from SA tree seeds.

I never used this mod for farming wood (I disabled auto robot harvesting) but only for the aesthetics of replanting forests.
Afaik this mod is the only one of it's kind that allowed us to mass place trees with bots and with blueprints.

I don't know how easy or hard it would be to make it compatible but if you could make it work that would be wonderfull.
I know most people don't really care for aesthetics and mods which use more wood in their recipes provide their own way of farming it, which is why this mod never had high downloads.

Well then, I am like you :)
I am also using dense patches of trees to protect some assets inside biter territory. Like power poles and radars.
I uploaded a new version, without testing it though. I hope I have disabled support for Vulcanus and Gleba. I think it would be silly otherwise.
Please report problems or glitches or weird things happening.

Thank you for taking your time with this.
I tried to test it but ended up with this error:

Bummer. I am not careful enough. Try downloading the same version again (1.3.5).

The mod now works for me and after some quick tests I'm not noticing any bugs so far.
Thank you for reviving this mod.
