This was a link for HM2, not HM3. We don't post HM3 links on the forums yet, as we don't have a HM3 sub-forum. We don't even want HM3 questions on the forums to be completely honest, until after HM3 is released and we have created the necessary HM3 forums.
I don't have an ETA for the next HM3 release, and am not sure if the same fix will be ready for HM3 once it is pushed to the next beta version. While we do not have an exact date for the release, you will receive a prompt to update once available as long as you have enabled the Tools - Settings - General - [x] 'Check for Updates' option then you can read what changes are available in the next HM3 beta.
