Mendo Ren does not appear after an encounter wipe

Tracked since 27 Aug 2026 · Last researched 27 Aug 2026

Problem

After every player engaged with Mendo Ren dies, the Siege of Orison encounter may fail to reset. Mendo Ren may be absent or stuck inside an airlock.

Applies to Alpha 4.10.x LIVE · Current

Best current action

Force the engaged team to respawn

Have every player engaged with Mendo Ren die and respawn, then return to the boss room. If the encounter is still stuck, repeat the forced respawn.

CIG says this resets the encounter, and one 4.10 team reported that wiping together brought Mendo Ren back.

What to do

  1. Have all players engaged in the encounter die and respawn.
  2. Return to the boss room and check whether Mendo Ren and the encounter have reset.
  3. If the encounter remains stuck, repeat the forced respawn.

All players engaged with Mendo Ren must participate in the forced respawn. All players engaged with Mendo Ren must participate in the forced respawn for the encounter reset described by CIG. This deliberately kills the team and requires another trip into the boss room. CIG warns that it may take more than one try.

Boundaries and evidence

Use this only after an engaged-player wipe leaves the Mendo Ren encounter stuck. It does not cover other Siege of Orison targets that fail to spawn.

Only one current independent team execution was found. CIG gives no success rate, and we did not independently test the recovery.
