So i'm stuck at the moment where you need to transform Baby Goal into lightning-conductor. I successfully gave her trees, the umbrella and set the pool on the platform. The problem is that i can't give her a prize ticket - when i give it to her Rufus automatically takes it back - it doesn't disappear from inventory. So if someone knows a way around this bug or can upload a save right after this moment (either completing antenna challenge or simply giving Baby Goal a ticket ) i will be very thankful.
Ok i was able to deal with this bug by loading the save before I acquired the ticket. Also I suggest to solve lightning problem before acquiring torpedoes - if | understand right this bug happened to me because i purchased torpedoes first so ticket became bugged.
