Character Tokens Disappear Upon Updating

Good morning!  This isn't a super big issue, though I figured posting about it would help at least.  In all of my games so far, whenever I make changes to the character sheet such as changing the current HP, my assigned token to my character sheet vanishes.  What's even weirder is that everyone else can continue to see the token.  While I thought it was just a simple graphic issue perhaps on my end, it turns out I couldn't even click the token where it was originally.  It literally vanished until the DM readded the token to the current map.  I'm not sure if anyone else has experienced this, but the players in my games have yet to see this. ** Update: I also forgot to mention that this has only started about a week and a half ago.

Before we dive into the guts of the issue, we're going to need you to do a few things for us, things that sometimes fix issues for users before more extensive troubleshooting is needed. Can you please follow Steps 1-3 of our Solving Technical Issues checklist (confirm you're using the latest non-test version of Firefox or Chrome; turn off all extensions, addons, and anti-virus; and clear your cache) to see if one of those components is causing the problem? We can only help if we can recreate your issue, so it is important that you follow each step. If doing that fixes the issue, just let us know. Otherwise, move on to Step 4 , and we'll need all that information to further assist you.
