Guile + opponent Reflections of Littjara

Opponent cast Mirym, Sentinel Wurm while Reflections of littjara is in play naming Dragons. I have Guile in play and cast a counterspell. Then the game rolled back and this error came up.

Here is the log.

Game exception occurred:

Start with mage.game.GameState.copyCard at GameState.java:1488 and follow the stack through GameImpl.copyCard, Spell.copySpell, and CopyTargetSpellEffect.apply. Reproduce the Guile and Reflections of Littjara interaction using the issue's sequence and log. Done means the game no longer throws while copying the spell and the rollback completes successfully.
