I'm currently stuck on the objective to upgrade a Engineer residence to a skyscraper. I've tried rebooting the game, my pc, building them on different islands and downgrading and then upgrading them again. Nothing works. Has anyone else had this issue?
If anyone knows of a fix or something else I could try please let me know lol. It sucks cause I can't unlock the rest of the items for the one store without being able to complete this quest.
