I've experienced a similar thing a few times.It won't stop me from playing and I'm grateful for Bytro trying to fix irregularities but since this thread is here...
On mobile when I want to construct buildings, Secret lab is the last unit building, there's a gap,then economy buildings,then industry...as mentioned there's a gap between secret lab and industrial building but if I click on the industry the secret lab starts to construct hahaha,it has happened a few times and as I mentioned there's a huge gap between the two,so it's not like I miss clicked... I just stop secret lab construction and click industry again then it will construct.
