I just updated Bobs/Angels and Miniloader and received the error message:

Error while applying migration: Miniloader (Redux): migration_1.0.0.lua

Unknown item name: bob-lithium
stack traceback:
[C]: in function 'newindex'
__miniloader-redux/scripts/config.lua:249: in function 'write_config_to_inserter'
miniloader-redux/scripts/config.lua:410: in function 'resyncEntities'

miniloader-redux/migrations/migration_1.0.0.lua:5: in main chunk

Did you happen to have this mod before and then disabled it? This sounds like there is a filter stored in the config and it is no longer known in the base game.

I could reproduce it. It is fixed in the next release.
