[2021] Suddenly became invincible as Sentinel

Can you show your sigils of hope tree please?

Can you show me your passive tree or a build planner of how you are set up?

Can you think of anything special that happened when the bug triggered? For example, you were spamming an ability or abilities or using a movement ability?

Can you show me your warpath skill tree?

Does this happen every 30mins? Or does it seem random?
