So I know there's been a bunch of glitches with this (and everywhere) but the data pack in Park Row where you have to hit a pressure pad and have 10 sec to hit two more, isn't registering for me (it's close to where banes guys were). I got the data pack but it still shows on my map, so can I do anything about it??
Same thing happened to me, but it is an existing datapack.
There will be a few times this will happen, where your map leads you to a datapack you've already claimed, yet the symbol is still there. You just need to enter whatever structure is there or near there and claim it.
Sometimes its underground, sometimes its inside a building, etc. Just have to get looking around and you will find it soon enough.
