"We’re happy to announce the release of Patch 1.20 for Warhammer 40,000: Dawn of War. This patch includes the following fixes to some of the most common bugs:
Seer Council ‘Conceal’ ability fix – It now only applies to individual members of the Seer Council.
Chaos ‘Taint’ ability fix – It now only heals in the second tier, but applies to Chaos Commander units as well as infantry.
2-minute Drop fix – Now players cannot drop out of games before the 2-minute mark without it counting as a loss.
Lobby Spamming fix – Fixed some issues with the lobby system which should decrease/eliminate spamming in the lobby."
