Details:
This happens when [store_unit] matched 0.
This used to be safe until two betas ago. Most of the time [store_unit] is on
a filter guaranteed to match 0 or 1 units so lots of code uses [unstore_unit]
without an explicit for-each.
The reality is [unstore_unit] and [set_variable] should probably be changed
to vector but too much of a breaking change for now.
Patch: do not crash on empty unstore_unit.
The_Tunnel.gz is a savegame from Story of the Wose where the role-based
recall matched zilch.
