My household has two PS4s. Today my wife and I were playing together, each on our own PS4. Later, we switched to split screen because my laptop died (remote play on the second PS4), but we discovered that her explored map had disappeared. The entire map was black. Her character, her inventory, all remained. But the map exploration was gone. Same server, same save file, same PSN account, lost the map.
Steps to Reproduce
Log into the game from a different PS4 on the same account, map is gone.
