Vaal temple party play, resurrection at checkpoint shenanigans

In the VAAL temple playing with two others, when one ore more of us dies, we cannot respawn at the last checkpoint. Its locked. We have the option to view another player, cycle players but the option to respawn is not enabled. This is in ANY room - not just a boss. More interestingly, when the last person dies, there's a split second where any already dead party members can respawn at the last checkpoint but this option is fleeting because as soon as the last person respawns, that option is no-longer enabled.

This feels like a bug. I don't understand why we cannot respawn regardless when its not a boss but to give us a very brief option to respawn and then have it taken away is maddening making the gameplay more arduous than fun for juiced temples.

One of many bugs or temple gameplay "features" that makes it feel VERY rough and frustrating when playing with a party.
