thanks for bringing this to my attention.

The Behaviours in question still ship with the latest version of Remote Buddy and should also get loaded automatically when launching Remote Buddy.

To determine which Behaviours to load, Remote Buddy consults OS X Launch Services and only loads those Behaviours that OS X Launch Services says it knows.

In the past, LSRefresh should point Launch Services to the right direction when correcting errors. The API LSRefresh uses has been deprecated by Apple with OS X 10.10 however, so I don't know if it still effective.

Just launching the apps in question should have the same effect, though. So if you quit RB, launch Safari and launch RB again, that Behaviour should also be loaded.

If not, there's still a chance that something went wrong during the upgrade and you ended up with a bad Launch Services database. Resetting Launch Services, then, should fix the issue. Here's a article on how to do this, should you need it:
