I have a Controller class with really boring code in it. If I go to the run->debug menu and run it, and then navigate to the page that is associated with the controller, no breakpoints will suspend. Period. The red circles have checkmarks in them indicating that I don't have them mistakenly set on non-executable lines. I've done a 'grails clean'. It only affects certain controllers, another with breakpoints will suspend.

All newly created controllers fail to suspend as well.

It has to be a configuration issue in IntelliJ, but it won't seem to budge.

Also happening, no idea if it's related or not: on the sidepanel in the Grails View, it's underlining Controllers" with red squiggles. None of the leafs in the treeview are underlined however.
