Valve removed two unique maps from Dota 2

Valve removed all mentions of the dota_mid and dota_keen maps, which were previously discovered by Mark “Sikle” Lerman

Many people hoped that the appearance of these maps meant a soon release of a global update with an event. Some even thought that a unique map with only one mid lane was preparation for a mode with living Thrones

However, for now the files are removed, and it’s unknown if the developers will bring them back. At the same time dataminers are noticing activity on Dota 2 test servers, which could indirectly confirm that an update is being prepared

Valve themselves have not made any official announcements yet, but dataminers expect the update to release sometime in mid or late May
