Progress bar going forward and backwards

I tried to enter a cooperative (in firefox) 10 minutes ago.

My progress bar slowly went to 100%.  Then to 0%.  Then to 80%.  Then to 0%.

I started to then capture it:



It then (from #0 to #5) went up.  Then it went backwards (#6).

Then it got stuck (#6-#10).  Its been stuck at #6 for about 7 minutes (Its still stuck as I submit this bug report).

Note: It also went up & down in the #0-#5 pictures, but I was not able to capture this until #5 to #6.

Thank you for the screenshots Joyce. It is something that has already been dealt with.

We will upload a fix later today.

I've had a similar thing happen to me today. I was doing a solo and the progress bar kept jumping back and forth by like 5% and once it loaded completely the battle would not start so I had to refresh.
