Wargaming's API for (at least) my account is bugged and I'm probably not the only one in the situation… I've noticed this for multiple tanks I've been trying to mark, but now I managed to get proof on a new tank.
Been trying to 3 mark my Caernarvon on EU and kept noticing that at some point the mod I was using kind of stopped recording an increase in percentage despite me having very good games. At first I thought the mod is broken, so I went to check WG's API for my account and compared it to the in-game recorded damage.
Results? In game I got up to 2276 total damage over 100 games (see screenshot), but WG's API only shows 1862 (mod was working fine)
Tried to reach out to Support, but they said it's out of their remit (what a surprise!) and I should post on their forum instead (not sure why this is considered a solution by WG support).
Purpose of this post is to make people aware, I know there are others like me who are trying to mark their tanks and it looks to be a fool's errand.
Anyone noticed this as well/has had a similar experience?
