We had the same issue. We actually have had extensive issues with POI names in our multiplayer random-gen world. Every single POI says the wrong name, and it'll say we're in random POI's while running out in the middle of nowhere. This only happened in our multiplayer game (random gen world). I played a solo game today, and everything was fine. So def just widespread issues in multiplayer compared to Solo.
Thank you for reporting.
The bombshelter_10 POI was still WIP. It's currently in the process of being tested, so it is questable and is in rwg. It will soon be localized with a proper name.
