I am writing this to see if anybody done this because I done it but it not popped up for me I wonder if there was some sort of bug To it
I've done this, albeit on PS4 but had no issues. If your saying the collectables don't pop up, try walking over where they should be and almost walking into the signs and fences. Gotta be close/on top of them to make them pop up.
I’ve done it and got the trophy on PS4. I did the whole thing in one sitting and the trophy popped fine - one that actually worked for me first try.
Same here im on xbox and got the trophy, they should do a trophy for completing every service aswell.
