Same here. I can only assume our spell detail is too low.

I can see it sometimes, though.

I'm glad to see someone else is having this problem. My efflorescence shows up only some of the times, which at first made me think I didn't actually understand how the spell works, but it seems that it is supposed to show up every time I swiftmend which means I guess an issue with my graphics (although I do see it sometimes) or it just gets added to the list of bugs we have going on now.

I've been using Efflorescence for a week now and this is the first I knew it was even meant to have a circle. Completely invisible to me.

You guys aren't the only ones! As a pally I've only seen consecrate a handfull of times since the patch, it actually shows the effect on the ground 1 out of maybe 9-10 times. Not that its still as useful as before , but it'd be nice not to kite things out of it all the time now because I can't see it.. (I've tried various detail settings, and toggled the "show projected textures" as well)
