​i just had a level 6 janitor vanish without a trace.

It was definitely not an MIA event (all bad events were greyed out from levels/skills), there was no dilemma, & they didn't quit. There was no notification at all; they just didn't come back from the expedition & no longer showed in the staff list. I had 5 janitors on staff & then suddenly only had 4 on staff.


Notes on what was happening at the time: 

Pebberly Heights, single plot. 
Campaign.

Two helicopters, one came back straight after the other.

Two staff members were on each heli (1 expert, 1 janitor on one, the other was 2 janitors).  

As the first finished it's return cycle, a story quest completed (2nd star) & a curator quest (7) completed.

One of the janitors from the janitor pair that went together didn't return (one was a level 9, the other a level 6) & they'd gone to the Bungle Burrows map for materials.
