Error with loading population

GA: Loading pupulation from file
Error data/script/evolve/evolib.lua:263: attempt to concatenate local 'res' (a nil value)
What does it mean? And how to fix it?

O ho, I haven't looked at this code in 10 years :)

Looks like it's failing to load a the population from a file:

https://github.com/windo/toribash-evolver/blob/master/src/evolve/evolib.lua#L263

I think you might need to set loadPrev to false on the first run here:

toribash-evolver/src/evolve/GA_default.lua

Line 30 in fb73add

c.loadPrev = true -- continue evolving the previously saved population

Then it wouldn't try to load the population that I guess does not exist on the first run. Instead it will generate a random population and then hopefully start evolving it. But then again, is it even reasonable to expect this to work after all these years? Surely toribash will have changed?
