With FL (https://mods.factorio.com/mod/FulgoraLives) + Lignumis I'm getting the following stack trace during Factorio startup:

Failed to load mods: ...numis__/prototypes/content/burner-agricultural-tower.lua:25: attempt to index field 'surface_conditions' (a nil value)
stack traceback:
    ...numis__/prototypes/content/burner-agricultural-tower.lua:25: in main chunk
    [C]: in function 'require'
    __lignumis__/prototypes/content/data.lua:8: in main chunk
    [C]: in function 'require'
    __lignumis__/data.lua:30: in main chunk

Of course this was going to be an issue. When I wrote the code I thought: "But what if a mod changes that... naaaa, that won't happen". Here we are :-)

Fixed. Please update. The latest versions require Factorio experimental version 2.0.33 or later.

Thanks for the quick fix!
