Our guild hall has Ore Synthesizer 1, Wood Synthesizer 1 and Plant Synthesizers 1. Before, there were 5 synthesizers total: 1 metal, 1 wood and 3 plants. I’m standing there right now though, and there were only 4.
I checked the patch notes to see if maybe they just decided they’d given us too many plants and decided to take one back, didn’t see anything about it. So just bugged maybe?
