Blizzard jumped into hot lava once again when they released the half-baked Warcraft 3: Reforged but they are working on fixing the mess. The first update is around 2GB in size and deals with some of the most frequent and game-breaking issues.
Replaying Warcraft 3 campaign in the glory of new graphics was in all fans' minds when Reforged was announced but Blizzard dropped the ball particularly hard in that section. Players were getting random defeats after loading into a mission which literally made the campaign unplayable. The 2GB patch with fixes notes that this has been dealt with.
Besides a slew of other smaller fixes for the campaign, Blizzard also fixed problems that blocked progression and wouldn't give players credit for completing objectives. This update messed with prior saves but campaign progression will not be lost.
When it comes to custom games, players found that crashing was way too frequent. In this case, Blizzard fixed multiboards which should deal with some crashes in custom games while joining lobbies for the same map will no longer create duplicate versions of said map. This change fixes the disconnects that happened as a result of improper map names.
Those looking to enjoy Classic mode can now do so without it feeling like a bad acid trip. Rendering in Classic is fixed and the graphics will not freak out like before. Furthermore, Blizzard added a filter on the main menu to distinguish Classic from Reforged.
Warcraft 3: Reforged will not spoil matches anymore as starting locations are once again obscured by fog of war while audio feedback is fixed since units training off-screen have voices again.
These are the highlights but you can check out the full patch notes on Blizzard's forums .
