There is an action in Reapack called JerContact_Open project based on file in clipboard.lua
Here is a video of Jeremy explaining what it does

The problem appears when you put files in render queue. After rendering you cannot use this function because the files have bwf data from temp project that was created only for rendering purpose.
So if I have project named test.rpp and render files using render queue this happens when I try to use JerContact's function:
I think that this is not the expected behaviour and that it should be fixed.
I'm working on script that will let wwise and reaper comunicate and I stumbled upon this problem.
