I'm not sure if anyone else has this happening, but I updated from 0.17.15 -> 0.17.32 on my server and client. Everything appears correctly on the map, but the electric miners are not working, just sitting idle. If I pick one up and replace it down, it requires sulfuric acid to start mining on everything, including coal and stone. The only error I see in my server log referring to sulfuric acid is for Angels Infinite ores of:
Script @angelsinfiniteores/prototypes/generation/resource-builder.lua:800: "sulfuric-acid"
There are no errors loading any of the Bob's Mods, so I'm not sure this is a Bob's Mining issue or an Angle Infinite ore's issues, but since it's the miners not working, thought I'd start here.
