Title: Fixes corner-case exploit regarding nar-sie and red alert

This corner case exploit is as follows:
Cult round,
Alert level is red,
Summon nar-sie,
Two minutes of recallable time,
Recall shuttle if lucky enough to not get eaten by nar-sie.

Although hard, if performed, the round would extend indefinetly unless
admin intervention is present, as nar-sie would kill everyone and nobody
would be able to call the shuttle again.
