Same for me on Android: the deep delve map is blank, just as in the OP’s screenshot.
Yep, and it’s ridiculous that this keeps happening. Art continues to be broken at release on mobile platforms; is there any plan to fix, or at least to improve, this?
This is also a good argument that beta testing needs to occur on mobile platforms, not just on Steam; if this had been spotted by beta yesterday maybe there would have been time to fix the artwork before it went live on prod. As it is: it’s broken on mobile, it’s the weekend in the devs’ time zone, so this won’t be fixed before the event is over.
