Team Spirit analyst Denis 'sikle' Lerman discussed a bug in Dota 2 involving Enchantress that can cause a server crash, through his personal Telegram account.
Lerman explained the steps to trigger the bug: players should pick Enchantress, purchase Aghanim’s Scepter, wait until 20:00 in the game, then go to the Tormentor. By stacking neutral creeps nearby and using Enchantress’s Aghanim's ability on the Tormentor, the server will crash. He added that the same result can be achieved with Winter Wyvern.
The bug works by making neutral creeps attack the Tormentor when Enchantress uses her Little Friends ability on it, leading to the game crashing shortly thereafter.
Previously, professional players encountered a bug involving Pangolier during an official match. On the second map of the series between Virtus.pro and Natus Vincere at the Clavision: Snow Ruyi tournament, Pangolier ended up outside the playable area.
