Since you were wondering wether or not it was a typo Nat, this is from the UNO sourcecode:

Ahh, thank you Learnminer! This is the answer I've been trying to get for some time.
I understand why people are opposed to raising the minimum block reward. I've even said in the past that I'm in support of UNO development as long as it doesn't touch the maximum coin count
or the block reward. I was just thrown off that people had been saying '250 years to mine!' for years, then when I ran the calculation it was 2,500 years.
I'll shut up about it (other than celebrating halvings) unless we run into related problems that may be caused by the 0.0001 reward.
Edit: Oh,
0.00001 
That's even lower than I was thinking, so actually there
is a typo on the website, just not in the direction I was thinking. So it's ~25,000 years to reach completion? Well like I said, we'll see what the hashrate and hashrate distribution looks like at that reward level.
Be sure to fix that part of unobtanium.uno Learnminer: "finishing with a minimum subsidy of .0001 after 15 halvings."
