Ahoy there,

So : Currently I have double turns on and it says Extend for 15 Credits, which I currently can do very easily... I just want to know , is it stackable so If i have 2 days , and extend it 3 times, will I have 6 days of Double turns or will it only last 2 days?

I hope you get my question,
Many thanks,
Mr Roberts

It stacks as you say. For every 15 credits you use, your time duration extends by 2 days.
