We've just added Heart of the Swarm dependency into NOTD. This will have the long-term benefit of allowing us to use new models/sound/terrain and additional Blizzard media. To do this, we had to remove some critical Wings of Liberty links from some really old NOTD units. (pre-2012). This may have a side effect of breaking several units/abilities. We're looking through all the unit links but because NOTD is such a large map, we may have overlooked things that can only be found through live testing. To ensure that we test this and fix any issues that will occur, the latest patch will only be uploaded in SEA server. We will test over 1-2 weeks to ensure stability before rolling out to all other servers by end-May. Please help with our testing on SEA (everyone can login via Global Play).
