New FAQ confirms spending a TL to reroll dice is a game effect
QuoteQ: What are examples of game effects that instruct a player to spend a target lock?
A: The cost for a secondary weapon such as Proton Torpedoes, using pilot abilities like Lieutenant Colzet, or spending a target lock during the "Modify Attack Dice" step to reroll attack dice are all examples of spending a target lock. Removing a target lock or assigning a blue target lock token to another ship are not examples of spending a target lock
