after removing a part or group of parts and putting it in the "garbage" the process cannot be repeated and instead the build just rotates and the cursor does not grab anything.
- Grab a rotator (on top of the boosters)
- throw into garbage
- grab another rotator (will actually not grab) instead attachment points all show up and the build will rotate but nothing can now be grabbed
@AndrewGarrison thank you, and sorry for forgetting to specify game version.
