Reconnecting an act in a telescope to a time rift removes the entrances
to the time rift from its access regions because it will be accessible
from the telescope instead.
By doing so early on, as a starting act with insanity act randomizer or
as a plando-ed act, this can happen before the time rift itself has been
reconnected to an act or other time rift. In which case, when later
attempting to connect that time rift to an act or other time rift, the
entrances from the rift access regions will no longer exist, so must be
re-created. The original code was mistakenly re-creating the entrances
from the time rift being reconnected, instead of from the rift access
regions.
