How to use Engineer (Sponser) ability?

[Starwarrior1128]

I just built a 2 space enclosure and want to build a 1 space enclosure as part of the Engineer ability. But after I built 2 space, it's asking me to confirm that my turn is over. What so I do? I don't want to mess up and have my turn over and not be able to build a 2nd time.

Engineer allows you to build a copy of one of the buildings you chose during the build action. It has to be the same building (so you can’t use the ability if you built the petting zoo, aviary or reptile) and you follow normal building rules.

Maybe you didn’t have enough money to pay for the extra building? Maybe you didn’t have the space to place it?

I think I didn't have enough money for the building. Thanks for the help.
