Triggering triggers via the admin menu does not execute wavespawners on servers

[Savolainen5]

I linked a wavespawner to a trigger. Firing the trigger via the admin menu works when I host a LAN server from my computer, but not on the server where the mission will run.

Executing the wavespawner manually also does not work, presumably for the same reason?

This has been working correctly on our servers lately, doing anything funky? headless on the server perhaps or something?

I can't think of anything weird I'm doing. No headless clients, bog standard trigger.
