Space Age, no mods. The asteroid collector grabber arm sometimes teleports between positions instead of moving smoothly.

What did you do?
I was traveling on a space platform to Gleba for the first time. I think the issue may be triggered by low power.

What happened?
The grabber arms teleported ...

I agree. It doesn't even need to be a button, just having any sort of redo would be great. Ctrl-shift-z or ctrl-y would be the most common. When you undo too far redoing is very necessary, otherwise random previous stuff gets deconstructed.
