(To clarify: this post is about not being able to move from a specific location in the world map.)

Attached is an image of the part of the map I've literally become stuck in (twice ^^;) since I cannot move from the spot via the directional keys. The only solution seems to be to "return" to base, e.g. give up the run and all progress, or quit the game - also without saving progress, of course. I hope this serves as a warning to other people not to lazily wander into the same spot but to stay on the path. ;)

Nasty! Thanks for the warning. You may want to rename this to indicate that the character is actually stuck on the world map. There are so many people who are stuck in the first dungeon in the sense they just can't get past it.
Also maybe add it to that other thread, I reported a few issues there: https://www.gog.com/forum/vambrace_cold_soul/version_103_is_live

Thanks for your response, hollunder.

I don't think I can edit an existing thread's title, but I added a line of clarification (hopefully) to my post. I'm hesitant to essentially double-post in another thread, but I'll create a link in there. Cheers.
