wrong comparison with boolean and int

[impaktor]

I've been offered several missions to transport a group of people, how many? 1.

Looking at the code, it would only have a group larger than one for flavour 0, but not for flavour 1 or 2, which also re groups, since false == 0 is false, or at least that's my understanding of it.

I think this will fix it.

Indeed 0 is true in Lua. Only nil and false are false. Big pitfall for poor C/C++ programmers ;)

Prefer 0 and 1

if x == false then false

if x <1 then false

Save space. :))

No, prefer true and false. Much easier to read and understand, and if you want to get really pedantic, marginally faster as well (on the order of single CPU cycles, but still).

Merged :)
