Code review comment for lp:~widelands-dev/widelands/ai-scheduler

uf, not a big problem, I am just afraid that some of these variables can achieve (or start with) negative values now - but I will test it all...

also a side question: game().get_gametime() returns int32_t - that means range of gametime -24 - +24 days. I hope game stops itself after 24 days of gametime..., is there some kind of protection there?
