I was going through the Dragon quest and at Stage 4 Step 3 I added the calendar but did not realize which refresh button the instructions were talking about to get the calendar to show up. I tried refreshing the entire page multiple times and the newly added events were still not showing up. Clicking on the arrow next to the calendar name and selecting refresh immediately resulted in the events being loaded. I think that refreshing the page should result in freshly loaded contents, and thus not require that I manually click the refresh button within the calendar menu.
