Hello, thanks for the mod.

Can you add some dependency on the agricultural science pack to research that requires it? Maybe it's because I have lignumis which unlocks an agricultural tower early, but the Tree Seeding Selection reserches are available to me before I have acces to agricultural science.

Hi, thanks for noticing!

Agricultural science is a prerequisite for tree-seeding, which is a prerequisite for the selection.
Except if you are using Krastorio2 Spaced Out, which removes tree-seeding tech, this workaround got introduced in 0.4.7 to prevent crash due to "nil" value.

Here is the bug on KSO2 side:

I don't have the krastorio2 Spaced out mod, but i have others. If I would have to guess its the compatibility with Lignumis mod. In Lignumis, the tree seeds are available from the start.

Thanks, that was valuable info.

Check out 0.5.1 and feel free to write with anything else.
