i cant start or load worlds with AMS Machines enabled
if i use Factory Planner https://i.imgur.com/XjP2QtJ.png

Hi, it seems that factory planner is trying to access the main product field of a recipe but it fails because there is no field of that name. I will look at factory planner's code and see what wrong, then I'll bring it up with them. (likely an issue on their end)

Update: I don't know what could be causing the problem on their end, maybe something to do with AMS rocket silos? QA provides a lot of debug info, can you post your logs?

Update: I've made a patch which MIGHT fix the issue. I'll test it now.

The patch should fix the issue once it gets accepted by the Factory Planner team.
You can track the issue here: https://github.com/ClaudeMetz/FactoryPlanner/pull/464

ok thanks
