On ESP32dev previously useable GPIO-16 cant be used in latest version

I was using version v0.13.3 and as per the instructions page I had my strip connected to GPIO 16.
Now I’m compiling the v0.14.0-b2 version from the source code and OTA installing it on ESP32. Everything is smooth, but if I try to change and save any LED Preferences, it throws “Sorry, pins [6,7,8,9,10,11,24,28,29,30,31,17,16] can’t be used.” and does not allow me to save.
Also the pin is marked in red text.
Please let me know what am I doing wrong while compiling?
I reinstalled my VSCode and PlatformIO once again.
To me it looks like some modification in pin_manager.cpp has broken it.

Thanks and Regards,
Sandeep

Not sure if anyone else faced this already. It was a mistake from my end, as my usermod file was using 16 & 17 GPIO pins and every time I used to compile this, it used to prevent me from using these pins for LED strip. Since it was not documented, I had to find it the hard way. Hope this helps if someone encounters similar error.
