[3.03] Enemy AI keeps switching targets without attacking

Observed with the Glanfathan leader at the end of the tutorial - he rapidly targets each member of the party in order, but never actually attacks.

Possibly the same bug as reported here.

I wish it were solidly reproducible, but it merely has a very high chance of occurring in that battle.
