Mods to disable:Failed to load mods: Error while loading item prototype "bi-seed-compressed-1" (item): Must have a fuel_value when fuel_acceleration_multiplier, fuel_top_speed_multiplier, fuel_emissions_multiplier, or fuel_glow_color are used.
Modifications: Tiers 32

Mods to be disabled:
• Tiers32

Doesn't seem to be a mod conflict, from what I can see. Everything else loads fine without Tiers32

Thanks for report. Is it item from bio industries?

Possibly, I'm not sure since it doesn't complain which mod is causing the error :( I can look in the logs if ya can point me in the right direction.
Other main mods I run are Bob's and 5Dim's. Tons of other smaller mods, but other than Bio Industries, I don't think they affect trees/seeds

I've tested, it comes from BI, the name of "bi-seed-compressed-1" says the same.

Fixed!
