I converted ~40 units while at population limit.
As I was at population limit the units died rather than being converted to me - I assume this is intentional.
When looking at the stats after the game it showed them as military losses for me - this seems unfair from a stats point of view.
On the graphs of military and total population my population dropped by the ~40 units and my opponents stayed the same rather than the other way around.
At the point of the conversion I had only lost 2 units up to that point but it jumped to over 40.
