Question About DEV Mode

I am wondering if something about the DEV Mode has been changed.
Several months ago, when looking at the Cessna 208B Grand Caravan, I was able to drill down to, for example, ‘Tools | Behaviors | Input Events | Lighting | Lighting_Strobe_1 | Add to Control Panel’ and on the right I could see the code that was used to control the strobes for the aircraft. Now all I see is “Code has been optimized away” and there is no code to be found.
Has it been decided NOT to ALLOW us to see this code, or has the procedure for accessing this information been changed and I just don’t know the new procedure?
Any insight would be most appreciated!!
