This is a problem with the Voobly client and it needs an update to recognize the new rec id introduced many months ago with v1.5 Beta R7. It's not even a problem with the complex stuff like handling the rec data, etc. It's just making it accept the "9.F" id instead of only "9.E" lol.
This should be a simple 30 second fix, but unfortunately the Voobly devs have been unavailable for several months and I have no influence there. If anyone at Voobly can get this fixed, it would be greatly appreciated.
