No portal appears after completing Drox fight in Mirage

After completing a Drox fight in Mirage, no portal appeared for me to use to leave the arena, had to logout to be able to leave. Bug report ID 2355107090.

Few potential preconditions/steps that could help to reproduce:

1. Open Mirage > Kill map boss > Kill Drox > Enter Mirage.
2. Both map and Mirage had Maven witness the fight.
