Will be Interesting so see how this will play out on the Dev's side.

Confirming Amber and Ender displaying same map data when using identical -U path's. (Thanks Romovs)

* Used http instead of https. (on both client)
* Included shared map markers. (of course)
* All characters (on same account at least (currently only use one active account)).

(Found Default client to not supporting -U option)

This worked like a charm! Changed it from "https" to "http" & it synced my Ender Client's map with my Amber Client.
