I'm currently using the encounter builder, and after I have selected my campaign, I'm trying to hide the characters that will not be able to attend my next session (as they are out of town), but when I click on the "..." ellipses, nothing happens.

I've tried this in a couple of browsers (chrome, Microsoft edge, even tried using the google app on my iPhone), but they all seem to have the same problem.

I know I was able to hide characters as recently as a month ago.  Have I missed something and/or doing something wrong?

Someone, please let me know.

Thanks! 

Make a new encounter without those players.

I am also getting that error. Clicking the "..." ellipses does nothing. This is a bug.

Same thing here, cannot adjust the characters in the encounter.
