Animation editor tools are completely broken

[Joe2500]

Describe the bug
When editing character animations using the "Advanced" Model Editor, the editing tools (translation, rotation, scale) are incredibly bugged.

When using the translation tool, 90% of the time you try to move something, instead of just moving it to where your mouse is, the selected part will glitch out and fly thousands of units away. Even the smallest of mouse movements will do this.

The rotation tool is incredibly hard to click on. Sometimes I have to spend 10+ seconds just trying to click on the rotation wheel since it will only let me click on a few pixels (I have the program fullscreened on a 1080p monitor).

Trying to actually use the rotation tool is a whole other issue:
-Clicking on a single rotation axis will sometimes freely rotate even though I clearly didn't select the free rotate option. This happens most often with the blue rotation wheel.
-The rotation tool also has a similar issue to the translation tool, as it will rotate the selected item incredibly fast at the smallest mouse movement.
-In order to make it work normally, you have to rotate the camera and position it at the perfect spot, which takes me about 20 seconds to find. This also works with the translation tool.

I don't use the scale tool, so I don't have any bug to report there, but I imagine it's probably fcked as well.

Finally, BrawlCrate will crash at any given moment. This isn't very common, but it's happened to me at least 10 times so far. At any given moment, the window will freeze, the blue mouse wheel will pop up, and 3 seconds later BrawlCrate closes, wiping all my progress.

To Reproduce
Steps to reproduce the behavior:

1. Import any .szs file with animation into Brawlcrate (I'm editing a MKWii vehicle file)
2. Preview the model (this enters the Advanced Model Editor)
3. Do the things I explained

Expected behavior
It should just work normally lmao
