Editing Forum:Categories take a while to update?

{{Forumheader|Help desk}}<!-- Please put your content under this line.  Be sure to sign your edits with four tildes: ~~~~ -->

Sorry if this is a noob question, but -- it seems to me that categories are taking a while to update.  A number of recently-created pages with categories just aren't showing up on the category pages.  For instance, if you look at [[Special:NewPages]], you can see a number of recently created tournament pages under the "2016 tournaments" category, which don't show up in that category (or any of their categories).  Examples include [[Paradigm Shift]], [[KSB 2016]], and [[Full Bloom 2]].  Is this an error?  Is this a known issue?  Is there anything that can be done about this?  Thank you!

:It updates immediately for me, although I self-added the category. What's your browser, and have you tried hard refreshing it? <span style="font-family:Orbitron">[[User:Megatron1|<span style="color:maroon">Mega</span>]][[User talk:Megatron1|<span style="color:silver">Tron1</span>]]</span>[[File:Decepticon.png|19px]] 13:09, 19 June 2016 (EDT)
::How odd!  I'm seeing it updated now too. Browser is Firefox 47 on Linux Mint.  What is meant by "hard refreshing"?  I've tried refreshing certainly.  I mean, it appears to be working now, but if there's some more general problem I don't know about, I have no idea if it's fixed or not.

:::Not a Linux user, but [https://wiki.scratch.mit.edu/wiki/Help:Hard_Refresh hard refreshing] is basically a super refresh. People have had similar issues with viewing image uploads, and that's fixed by hard refreshing. It would be logical to assume that it also helps with categories.
:::Anyways, if you spot another instance of this problem, make sure to hard refresh first. If it still isn't fixed, just bring it up again and one of us can look into it some more. <span style="font-family:Orbitron">[[User:Megatron1|<span style="color:maroon">Mega</span>]][[User talk:Megatron1|<span style="color:silver">Tron1</span>]]</span>[[File:Decepticon.png|19px]] 21:50, 19 June 2016 (EDT)
