Tutorial can be broken

I've broken the very first Tuto by clicking on the ACU and by moving him to another place. This has canceled the ACU's build queue.
Then it was impossible to make him to build up a factory or some Power Gens, however I've managed to build up the Mexes...

Yeah - these are very fragile. We're open for contributions to them, but we have nobody with sufficient time and experience to pick them up.
