I got a blessing from him a few days ago and I'm still seeing the fiery kiss mark on my avatar's cheek.. i did not get any new blessings since. is it supposed to stay that long or is it a cache issue (or a different glitch)? I'm seeing it both on my android phone and on my windows 10 computer.

I found that when it was sticking around too long, going into the wardrobe and clicking "Wear" again on your current outfit (you don't have to make any changes) refreshes your avatar and makes the mark go away.

Yeah I noticed this, too. Pretty annoying.
Thanks for the tip, . I'll be using that.

thanks for the tip, that helped :)

You're welcome; glad I could help!
