unless you had your custom campaigns and maps loaded in another directory, or backed up. when you downloaded WC3 reforged it wiped customs maps stored in your directory.
WC3-FT blizzard never established rights to maps, games, campaigns created by the world editor that came with the game, this editor also had some SC tuff in it too.
DOTA was started using it, as a WC3 fansite function and was allowed, once DOTA launched independent went under Valve blizzard sued, DOTA2 blizzard sued, mobile games using WC type editor blizzard sued, some settled out of court, imo overall blizzard lost and this continued with League of Legends (LoL) which claim it was inspired by WC, from what i understand they used editor in same fashion or copied like DOTA did

blizzard did HOTS 11 years to late, so i see why they are doing what they are doing now with WC3 reforged in protecting everything. DOTA and LoL turned players into millionaires while HOTS broke players and blizzard.
i was a WC3-FT diehard, but blizz canned us into severe less than HOTS maintenance mode, they saw no reason to continue further on with it, DOTA and LoL proved them wrong...ironic there is a lol there
