There has been issues with them showing off and on over the past couple of weeks or so. There are a lot of changes happening behind the scenes at the moment and in my completely not having a clue at all about the technicalities of the issue, it's apparently a cache issue on our side.
I'll make sure that the people "in the know" are aware of this thread but all I can really do myself is to apologise and ask you all to be patient just a little bit longer with the avatars as I'm sure people will be pleased when the changes go live.
Thank you. 😊
