When showing the number of countries in your collection (both in "My coins" as in "profile"), it counts all countries you have coins of (both in collection and in swap), while the issuers are only counted for the coins in your collection.
For me, only collecting Europe, it thus gives the weird count that I have 140 countries but only 70 issuers!
Countries should also only count the number of countries of which you have coins in your collection, excluding the coins you have for swap.
Just call me Bram
No new swaps for the moment, still too many half-ongoing swaps to clean up!
