Error while running event SupplyDropRefurbished_Continued::on_research_finished (ID 22)
LuaTechnology doesn't contain key effects.

This is an error in Suppy Drop Refurbished Continued. If you check the API documentation for the Control stage, you can see that LuaTechnology does not have "effects" it is LuaTechnologyPrototype that has the "effects." Mobile Factory simply sets "researched" to true on that line for a single technology which is added by Mobile Factory.

Looking between LuaTechnology for 1.1.110 and 2.0.77 "effects" was removed from LuaTechnology likely in favor of removing duplicate data that can be found on the prototype

Thanks for looking into this and for the explanation.

That makes sense. I'll update Supply Drop Refurbished Continued to stop relying on the old "effects" field and make it compatible with the newer LuaTechnology API.

I appreciate you taking the time to track down the cause of the issue.
