After updating to bob's mining 0.14
I get this at startup

"Failed to load mod "Bobmining 0.14.0
bobmining/data-uppdates.lua:23:
boblibrary/technology-functions.lua:152: attempt to call global 'log' (a table value)"

Playing factorio 0.14.5
it works fine until I updated bob's mining :/

I have the same problem. Replacing all occurences of log() with print()
in boblibrary/technology-functions.lua fixes it.

The bug gets triggered by some other mod that causes bob to complain about missing technology. In my case it's angelsrefining (using the older 0.3.0 version thereof fixes it for me).

Thanks that fixed the loading problem :)
Now it's back to Factorio :D
I too play with angelsrefining so that might be a problem related just to angels mods...
