They've implemented a refresh page cap.
Due to the popularity of the Bellisseria continent with the Traditional and Houseboat options, we have implemented a refresh limit on the home selection page to help reduce server load.
If running a browser plug-in or using a feature built into your browser, please set your refresh configuration to the following:
10 Page loads per 10 Minute period
Which means that you can exhaust those 10 page loads in the first minute, but will have to wait an additional 9 minutes before you can see the inventory page again.
