Can't translate any objects in editor

When I select an object in editor and click and drag the translation arrows, the object doesn’t move. However, when I type in new coordinate location in the Details menu, it properly moves the object. The rotate and scale tools still work in editor - it’s just the translate tool that is not working. It was working and then suddenly stopped as I was doing level building.

Any ideas how to fix this?

Problem solved. My grid snap value was set to 5000! You can see it in the top right corner of the gif. Yes, it took me over an hour to figure this out while working on other things.
