the error was an error, human error.
Damn silly human component of the game messed up and missed the second create creeper click.
I know this cos it happened again, and I checked I still had the 100 gold unspent, so I maybe clicked and moved away mouse too quick, or clicked cretae miner and didnt see 'you dont have the gold to create this unit' pop up.
Maybe, if you remove the human component, make the game play itself Ai vs AI, that will get rid of theses silly human errors which keep poping up in game :P
I had a bug, and what I say is accurate;
As chaos I spent all 500 on 2 miners and 2 crawlers, as a standard start. But I only got 1 creeper.
I know its fact because all my gold was spent (so I didnt click once by mistake on the creeper button)
Also it was before a single contact between empires, so it wasnt killed.
My first crawler went to the tower as normal, the second just never showed up.
It could be that it was stuck on a graphic somewhere? but I dont think we have collision detection with the castle, as I've seen miners walk through the wall (exit castle in a straight line from garison to gold - trough the wall.
At the time I didnt think to check population count, which would confirm if it existed in game.
It was just one crawler, and I had an enemy to crush :)
