This is weird

This afternoon I was dropping my cards on my other blog, I know that I dropped a lot already but I never expect that I am already at 300 drops. When I checked my dashboard and the numbers says that I had drop only 272, so I tried to drop again and every time I click they said 300 per day. I refresh my Entrecard many times but still 272. This is weird; this is the first time happened to me, how come I dropped 300 already if it is only 272. I really don’t know why is like this.
