[Navmesh] Barrier Device keeps blocking AI path.

Summary

I’m trying to use Barrier Devices with AIs (sidekicks) but even if I try triggering the “ignore agent” function on the NPCs, it doesn’t affect their navmesh/collisions and they end up stuck.

Additional Notes

  • I tried changing trigger’s components collision preset to different values, but none of them works (ie FortPlayerHoldingArea).
  • I tried disabling “Can ever affect navmesh”.

I’ve seen people reporting the same issue on the internet/discord groups, so I guess it’s not project related.

Forgot to mention “Physics” is enabled in Island Settings!

FORT-1125211 is ‘Closed’ as ‘Fixed’. The issue will be addressed in 42.00.
