All mouse click events stop working on build

[indeed]

Events triggered by a mouse click do not work in the build, but they (sometimes) work if I run the build while in Play mode.

- OS X 10.11.2
- Unity 5.3.5
- Playmaker 1.8.1

PS this has already been brought up in a thread http://hutonggames.com/playmakerforum/index.php?topic=13128.0, but I wanted to put it in the official bugs section. The "solve" in the thread feels like a hack and it's a bit scary for something as major as all mouse events. And it doesn't always work.

Have you tried adding an Event System? I need that to have any mouse clicks affect my UI. GameObject/UI/Event System.

If it's not your UI this probably won't help.
