Bug with respawn attempts for waystones

I was running a waystone with max mods (0 respawn attempts). Partway through, my guy died and when I went back to my hideout, there was no longer a portal as to be expected. A bit miffed, I decided to play another one of my guys from the same league. To my surprise, a portal showed up for that guy and I was able to pick up where I left off with the waystone and complete it.

I assume this isn't intended because 1 try effectively means 1 try per character you have in the league.
