Adventure mod Divining rod's sound

I found something weird when I playing Don't starve in adventure mod.

After i equip divining rod (radio thing to find 'thing's), after the signal sound rang out, it won't ring anymore.

Before updating hamlet early access, that sound rang like beep , beep,  beep, ...... (character says getting close or something).

But now it only sounds 'beep'. That was end, and doesn't ring anymore.

Of course, I disabled all modes, check options, check the game files(in steam option. verify integrity of game ---), tried all I can imagine to fix this happening.

I'm using Window 7  professional k -  64 bit

I don't have any files to show, but Iif you need any video files or something, contact me anytime.
