System Information
Windows 10 Pro and NVIDIA GeForce GTX 1070

Blender Version
Broken: 2.80 Alpha 2 Date: 2018-11-01 00:45 Hash: ae87adc73a Branch: blender2.8
Worked: (optional)

When trying to move the camera around a scene and add keyframes, whether I'm using the G key to grab and move with my trackball, or use the X, Y, Z on the N panel, sometimes, the camera will return to its previous position, and sometimes it won't. I can't figure out a pattern. I cleared all the keyframes. It seems to have the same issue while rotating. It seems totally random when it works and when it jumps back.

Exact steps for others to reproduce the error
insert camera into scene.
Grab it. Try to move it. Sometimes it jumps back to previous position, sometimes it doesn't.Inside the Science.blend

I've cleared the origin, rotation, etc. and that doesn't matter.

I cleared any parentage.

Or maybe there's something I'm missing?
Based on a (as simple as possible) attached .blend file with minimum amount of steps

Surprised there aren't more complaints about this problem. I run into it everytime I animate the camera in a Blender 2.80 build.

My workaround is:

at the new keyframe position (the one that keeps resetting) make sure you hit "i" to insert a keyframe on the x/y/z camera location.
Open the graph editor and find the new keyframes created for x,y,z at the keyframe position.
Press "n" if you want to see the side panel (which will show the numeric position values associated with the new keyframes) and change them there. Once the location values are changed in the graph editor they will "stick" and stop being continually reset.

Steps 1-3 may need to be repeated for each new camera keyframe position. Its pretty irritating.

I can confirm the problem still exists in Blender 0661bcba3210-win64 from 12/27/2018. This has been behaving oddly for at least a few months. At least its easy to reproduce.

Thanks, Ian. I'll give this a try with the newest build. Also, have you / has anyone else noticed that in the dope sheet, there are issues with the text of the selected object(s) not becoming bold, and its line not being highlighted? Seems like sometimes it works and other times it doesn't.
