@ThyReaper that was the problem! The construction can't be started when a creep is at the position.

CLOSED

I observed twice, that I can't build a ConstructionSite. To check that I stopped my Code (deleted main.js). Then I have a creep close to the construction and executed:

> Game.creeps.Riley.build(Game.getObjectById('577b07752fe3a52e25d9abde'));

< 0 

But the Command didn't work. After some ticks it worked then.... Around Tick # 11726786 (W13S37).

Nice Changes. The public ramparts are the first step towards diplomacy and guilds.

Also the changed costs of renewCreep are useful. Before, the function was only useful in very special cases.

nice idea. upvote.

The game became Pay-To-Win, because to more CPU time you have, the more you can optimize your movements. Especially in war situations. Nevertheless, I changed that comment. BTW, I'm not angered by the recent change. The game dynamics develops in a very good direction.
I'm not interested to sympathize with you. I just promised in the screeps chat, that I share my code after I stop playing.

Hello,
you can watch out my Code on Github now: https://github.com/sscholl/screeps
I stopped playing. so it is for free usage. Please "star" it, if you use it.
Bye

I'm not 100% sure, but I think I also noticed this behaviour.

I pressed both buttons, the blue and the yellow respawn button. But was not able to respawn. My Controller still exists.

Haha, can't understand that with my object orientated mind. I develop by just adjusting the prototype of your classes and creating ne "classes"

Oh, you are right. That looks like a bug!
