Started round with 0% production on tanks until this point. Had the war page up before I switched production to 10% tanks and troops which was also 0% until this point. Spent 10 turns and gained 270 tanks & 1240 troops. Went back to my war page and hit the "Refresh Military Information" button, troops updated (since you start with 100), but the tank count remained not shown (as if I had 0) until I reloaded the whole page.

Just a heads up if you didn't know, pretty minor annoyance.
Thanks again for the awesome game!
