AUTO DISCONNECT IN SOME CUSTOM MAPS

[Cord3L]

When I create the map to play on lan with my friend, and he presses to enter, it appears that he entered and soon after (1s later) we are both disconnected and return to the map listing page.

It happens with a specific map, (just the one we want to play) [NCD S1 v1b, specifically].

We are connected via hamachi, and playing on W3 version 1.31.

In case you get the disconnected problem when your friend tries to join your lobby:
The map you plan to play MUST be in the same directory (usually in "Documents\Warcraft III\Maps") and that the map/filename MUST be the same.
Also, if you try to play the custom maps from the Discord, you must remove the "_", as it's still considered a different map/filename.
