Counteraction answers follow the FAQ: absorb reflections, not shields

"It's not letting me cast Absorb Spell on your Full Shield" — and
Jolly's FAQ says exactly why: "ABSORB SPELL will work on FULL
REFLECTION or REFLECTION, but not FULL SHIELD, as that is not used
against you, but cast upon the player using it." The refusal stands,
now with that reason in the error — and the neighboring case the
engine wrongly refused is fixed: an attacker may answer a reflection
with ABSORB SPELL, nullifying it and taking the reflection card into
their hand, with the original spell then landing unturned.

And the card face corrects my own hours-old work: ANTI-ANTI "does not
work against escape, such as SHRINK, TELEPORT, or INVISIBLE" — so
under rules rev 6 it can no longer pin a teleport escape. Earlier
games keep their stored chains.
