0.1.0d Hotfix 5

I don't understand, the hotfix is :

"Fixed a bug where The Trail of Corruption quest in Act 2 could fail to progress when clearing the Sandstorm if you disconnected during it's animation. Those who were progression blocked by this should be able to use the marker to trigger this event again."

But they change other things, why there is not a mention about this ?
For example, we can't respawn and farm bosses anymore with this new hotfix, why isn't it mentionned ?
