Ich finde es schade das manche Namen englische Schreibweise nicht mit dem Spiel bei einstimmen dass man die NPC nicht genau zuordnen kann

I have posted some missing info on the Gamer Guides discord's BDSP section, but if I should post it here instead give me a heads up!

Edit: When I come here to write a new message, the textbox says that this would be the first comment on the page; however there already are a couple of them. Is this something that's possible to look into?

Thank you so much for this map! It was very helpful to locate traders and TMs.

I'm not sure if this is the right place to discuss it, but there are two things that I have observed and that aren't present on this map: 1. There is a Small Sphere trader in the corner just south of the Icy Cave in the Stargleam Cavern area (center area) 2. When entering the underground from route 213, depending on the player's position on the route, it is possible to access the Bogsunk Cavern area (southeast area); however I don't see the route's Entrance/Exit label anywhere (not even on the big center part).

If you are aware of these and there is a reason why they are not there, please let me know!

We have now added the Small Sphere Trader NPC to the map in the Stargleam Cavern area.

Thanks, that's a massive help! I've added some more entrances from Route 213 now. It's quite useful for visiting the south-east section of the underground early.

Good to know that you're keeping the map up-to-date! If I find anything else I will leave a comment ^^

Edit: Actually I have a comment now that I think of it.

The route 213's case is actually more complex (actually, maybe more simple) than I initially thought.

According to my short testing, the exact spot you end up when entering the Grand Underground (usually in the middle of a corner/intersection) depends on which square you are on the map at the moment of digging. That means that routes and towns that are bigger that one "square", as seen on the town map when navigating with the D-pad, can lead to multiple places underground; hence route 213 leading sometimes to the wide center area, and sometimes to the south-eastern area.

I hope this information could somehow be labeled correctly on the map so that routes leading to different areas aren't wrongly displayed! (This would lead to a lot of information on screen though).

Hope this helps!

Hi there! This map is still a work-in-progress and not yet fully complete. Thank you for bringing this to our attention. We will update the map accordingly! ????

A godsend of a map. Thanks so much! Btw, I found Guy where Reade is indicated.

Hi there! So there is a random chance for any NPC to spawn in the vicinity of the marked NPCs. The named NPCs are however most likely to appear in the areas marked on the map.
