Not sure if this is a bug or if I'm missing something completely obvious (which is not out of the realm of possibility), but I would like to buy a Scientific Development Center wonder and it is not available on my "choose the wonder you want to buy screen." Other wonders are available, just not the SDC.

As far as I can tell, I have all the requirements to purchase one:

Krack of Krackmerica

1. Great University
2. National Research Lab
3. 14,000 infrastructure
4. 3,000 tech
5. $150,000

$150,000,000 - The scientific development center increases the productivity of your factories from -8% infrastructure cost to -10% infrastructure cost, increases the productivity of your universities from +8% citizen income to +10% citizen income, allows the Great University to give its technology happiness bonus up to 5,000 technology levels (+2 happiness each 1,000 technology levels). Requires 14,000 infrastructure, 3,000 technology, Great University, National Research Lab.

Is there possibly a bug going on here?

Checking your charts, your infra isn't actually 14K, it only rounds to display as such. It's actually: 13,999.997. Buy a little infra and you should be able to buy this wonder.

Thanks, that did it. Consider this "not a bug" - however, we might want to look into rounding down instead of up to avoid further confusion on this.
