I've tweak your mod to start with really fast bot for instant construction (too slow for me for building my start/mid game).

I'll give you the code if you're interrested:

--Freeplay
script.on_init(function(event)
local speed = settings.global["faster robots"].value
if not(speed == 0) then
for k,v in pairs(game.forces) do
for z = 1, speed, 1 do
if z < 6 then
v.technologies["worker-robots-speed-" .. tostring(z)].researched = true
else
v.technologies["worker-robots-speed-6"].level = v.technologies["worker-robots-speed-6"].level + 1
end
end
end
end
end)

With this code, you can remove, maximum value settings for faster robot.

With this code, you can remove, maximum value settings for faster robot.
worked like a charm thanks

worked very well with seablock, pyanodons and kras2, now in the last version of kras2, the limit is on again :(

Getting this error, when trying to use with kras2+SE
