Selection Tool Broken

[Bobytoeburrito (Innovator)]

Description
While building, I was attempting to click parts when suddenly I was no longer able to deselect the previously selected part. I do not recall if I simply clicked or briefly used ctrl + click. Clicking on other parts or on nothing would not deselect the part. I was able to resolve the issue by deactivating and reactivating the select tool. This issue was accompanied by an error. While I was not actively using any, I do have plugins installed.

Reproduction
Could not reproduce

Actual Behavior
I was unable to deselect the previously selected part. This issue was accompanied by the error listed below.

There will be a fix for this releasing this week. Until then you can turn off the Dragger Improvements beta if you don’t want to run into it.

This should be fixed now, let me know if you still run into it.

Is the issue that causes this tied to changing the parent of the object? It’s something I’ve noticed for a while now and seems to be centered around that. Is there a particular factor in that process that causes that persistent selection? Always wondered from an engine code standpoint what it could be.

The cases I’m aware of where this was breaking were just some missing nil checks in the updated dragger code under the QoL beta, which I’ve gotten an initial set of fixes for out now.
