The Devs of "Magic Storage Extra", are pointing HERE, to this thread, in the GitHub... Also noted that the main Dev, of (Magic storage) is also on the (Magic Storage - Extra) mod. They are the reason there is so much confusion.
Adding insult to injury (confusion), the tModLoader (browser), shows that (Magic storage) has not been updated in half a year, but (Magic storage - Extra) has been updated 20 days ago.
I think the concept is great, but hearing how everyone is losing everything... Kind-of reduces my desire to risk trying it out, unless I make a world-backup program.
I am not even sure what the difference between the two mods are. They both seem to have the same, generic and vague descriptions. One pointing to a GitHub, which is a horrible choice to direct USERS to... (Which then points back here.) Then the original program points to a forum thread, which has lots of detail but many broken images of the way to use the storage. Kind-of critical when using images to SHOW how to connect things, and the images are not there.
