I was at the maximum of my contacts capacity so I spent 100GP to buy 20 more, and apparently only 10 were counted because after adding 10 contacts, I was told I had reached my limit. I have seen my 100GP being deducted so there is no mistake at this point, I've bought 20 contacts.

I currently have 106 contacts and it seems strange that it's not a round number... How many available contacts did we start with ? 50 ? I doubt it to be 56 or 66, but it would be the only explanation to it, since we can add contacts by tenths only.

Plus I'm not sure it's the first time I have a problem with the number of contacts, I haven't paid attention before but I may not have had 10 more contacts each time I spent 50GP.
