Loaded my 1.0 save up today and noticed that the area mining drills do not migrate properly. (see attached screenshot)


The migration downgraded the area mining drills to regular mining drills. This was in the current 1.1.x experimental version.

Thanks for the report however that's up to what ever mod(s) you're using to handle. Those aren't base-game entities. The mod defines how it wants things to migrate and the game applies that migration. In this case it looks like the mod defined them to migrate to vanilla entities.
