Title: Missing AirVLN-E memory graphs and preprocessing scripts

Hi authors,

Thank you for releasing CityNavAgent.

I downloaded the AirVLN-E annotations and the provided CityNavAgent_Data.
The AirVLN-E annotations contain 100 tasks across environments
1, 4, 5, 6, 7, 9, 11, 12, 14, and 16.

However:

1. None of the 100 AirVLN-E task IDs match the files in mem_graphs_pruned.
2. The global mem_graphs are missing for most AirVLN-E environments.
3. I could not find a script in the repository for generating the semantic
   memory graphs and episode-level pruned graphs.

Could you please provide:

• the complete mem_graphs for AirVLN-E;
• the episode-level mem_graphs_pruned for AirVLN-E; or
• the preprocessing scripts and instructions used to generate them for
  the AirVLN-E experiments reported in Table 2?

Thank you.
