Steps:
1. Execute the two pet actions, such as Fey Blessing and Whispering Dawn
2. Use the "Place" command between Eos/Selene after it uses the first command.

This happens with all pet actions when used after Fey Blessing. If you execute "Place" after Fey Blessing, Eos/Selene will not do the second action. It still goes on cool down, but it never gets used.
