I'm trying to load your mod along with Planet Maraxis and it's generating the following error: "Failed to load mods: Error while running setup for entity prototype "agricultural-camp" (agricultural-tower): next_upgrade target (agricultural-tower) must have the same fast_replaceable_group (agricultural-tower-3x3 != agricultural-tower)." Then it lists early-agriculture 1.1.2, PlanetsLib 1.15.0 and maraxis 1.30.59 as the culprits.

I'm really interested in using this mod to help me run my factory on renewable resources. Thanks for putting it together!

Actually it appears to be an issue with Agricultural tower mk2. I disabled that one and the game loaded fine with Maraxis and Early Agriculture both enabled. I'm not sure why the game engine decided to drag Maraxis and PlanetsLib into it.
