What are you attempting to achieve? Moving a part/model
What is the issue? The Model/part goes haywire and decides to move somewhere I am able to reach sometimes. It usually goes to the corner of the part that is touching the part/model
What solutions have you tried so far? Holding the ALT key (which makes moving precise) is the only way to make it work.
What build tool GUI is showing up in the bottom right corner of your screen?
If this is the standard Studio drag tool, what is your Increment on your Move tool set to? If it’s a very high number it’ll place items at the corners of the Part you are putting them on.
