Annihilator award wont spawn after killing all pigeons (IV)

[ProbablyWorth]

Killing all 200 Flying Rats rewards the player with the "Endangered Species" Achievement/Trophy, 2.5% to the 100% Game Completion percentage, and an Annihilator on top of the MeTV building in Star Junction. The helicopter hardly ever spawns if the player uses the window cleaning platform, and has a better chance of it spawning by using a helicopter to reach the top, which is extremely illogical, unless the player is using another kind of helicopter and wants to use the Annihilator.

An annihilated is supposed to spawn on the MeTV building but only does in a certain way. I don't think this is intentional by Rockstar
I went far away from the building and went back using noclip yet it still didn't spawn. Fusion Fix nor Various Fixes addresses this
