EOC_LIEUTENANT_SHADOW_SPAWN_MESSAGE errors

### Describe the bug

Was back at my base with a mild cold, cooking up something on the campfire, when out of nowhere, multiple errors:

ERROR : src/generic_factory.h:478 [const T &generic_factory::obj(const string_id &) const [T = effect_on_condition]] invalid effect_on_condition id "EOC_LIEUTENANT_SHADOW_SPAWN_MESSAGE"

ERROR : src/npctalk.cpp:2342 [talker *dialogue::actor(const bool) const] Tried to use an invalid alpha talker. Callstack: Spell: LTNT_LIFE_DRAIN Caster: the A shadow? \ EOC: EOC_LIEUTENANT_DRAIN_LIFE_TERRAIN

I'm pretty sure that was a cool event that I just survived (there was a shadow, and some swarming amalgamations), but I'm not sure if I got the event as planned. I'm pretty sure the errors weren't planned.

The only messages I got were:

- "The shadows recede, leaving you with nowhere to hide!"
- "The ground blackens before you"
- "The wind laughs through the night... but it grows more distant for now."

### Additional context

_No response_

Start by examining the EOC_LIEUTENANT_SHADOW_SPAWN_MESSAGE and EOC_LIEUTENANT_DRAIN_LIFE_TERRAIN references, then follow the reported paths in src/generic_factory.h and src/npctalk.cpp. Use the attached save to investigate the encounter if it can be loaded. Done means the event no longer emits invalid effect_on_condition or alpha-talker errors.
