my game didn't unpause when leaving lab, so a tried the command you post in the discussion to unpase the game and it return an error in the first for loop,
Im not a lua programmer but changing the code to the code above worked, at least on nauvis.

for j, entity in pairs(game.surfaces["nauvis"].find_entities()) do
if entity.valid and entity.unit_number then
entity.active = true
end
end

You know a way to turn on the achievements?
