Just noticed that the gyrobombers ranged attacks have completed stopped after Woodelf DLC.
They seem to maybe had the idea of having the gryobomber circle an intended target so you can bomb them easier, but now they won't fire at all.
There is still some fire capability though, as i got them to trigger a couple times in my testing, but they always go back to not being able to fire.
In my last test, towards the end of the game, they even stopped being able to attack the ground. very weird....
Let me know if you would like a replay file of it.
