OSC Go key (/eos/key/go or go_0) not working in 2.8.3-2.9.0

While designing my last show I noticed the Go key on my TouchOSC layouts wasn't working. I assumed there must have been a change in the OSC to key mappings, but the listing at the rear of the manuals hasn't changed.

I've confirmed the nomad software is receiving the correct OSC command, and neither /eos/key/go nor /eos/key/go_0 works. /eos/key/stop or /eos/key/stopback both work correctly (with equivalent function), as do all other keys and inputs tested.

I've since had a couple of other users of my layouts (available on ETCLabs/OSCLayouts) complain of the same issue. Is the cause known/being addressed?
