when starting new world you cannot do annything since you need a lab. but it need normal belts and that is locked behind research

Oh good catch. I'd mostly been testing new world completeness with AAI Industry, so I completely missed this, my bad! This should be fixed with 2.1.1, replaced them with inserters in the lab recipe. It's a bit more expensive than vanilla, but with the mod a pair of transport belts and an inserter is the same cost, so it's only 2x the cost.

thanks for the fast update
