Start by tracing CustomUnits.LowVisibilityAPIHelper.SetArmorDisplayActive through LowVisibility.Integration.CUHooks.ToggleTargetingComputerArmorDisplay and the CombatHUDTargetingComputer_RefreshActorInfo.Postfix shown in the stack trace. Reproduce the targeting-computer refresh with the Anti Aircraft Generator target; done means the null-reference error no longer occurs and the UI does not lock up.
