Imho, I find it quite embarrassing that blizzard left this issue in the game for over half a year already since they
acknowledged it, especially when it should be so easy to fix (if it's not easy, I'd love to hear why). I watched Abelhawk's stream on youtube and seeing him struggling and unable to start this map was very frustrating for me to see.
This isn't even the only map that is affected. Another recent example I came across is
Forest Party. And before you say this isn't an issue because map authors can easily fix it themselves, or that it is their responsibility, be aware that older maps with this same problem may be protected and its authors unreachable.
I'd also like to mention that the workaround for mapmakers of making a second force can affect gameplay, for example you are unable to share control through the F11 menu with players from a different force, even when everyone is intended to be on the same team.
In conclusion, it is my opinion that blizzard should deal with this issue, not mapmakers.
