Hi guys, 
Thought I'd just say hello!
Cannot believe I'm still playing this game with the lack of updates but I suppose it's hard to stop after 2 years!!!

Hopefully the update comes soon but I'm not holding my breathe considering the last video message from our poor little over worked Boom developers!!!

 

I didn't find the right solution from the internet.
