Sometimes I've had "Error: Couldn't load the map \n [OK]". Could you include some likely reason for this, i.e. what it actually means?

At present the user has no idea of what went wrong or how they can fix it, which reduces confidence.

If, for instance, it's due to the start zoom being wrong, that should be set as a catchable case with a specific error message.

Naturally, avoid piping through a technical error code directly through to the user. Ideally have a lookup table that converts a technical error code/text to a short user-friendly error message.
