Sometimes when I am selecting specific parts, I experience a weird issue where a part that I did not select is suddenly included in my selection. I do not know the reason for this and am unsure if I can replicate it easily.
This is problematic as it can cause me to affect said part that I never selected without realizing that it had became selected.

Expected behavior
Roblox Studio should only select the parts I click on.
From testing, seems like this could still happen if you select an item from the viewport that has not recently been expanded out all the way in the Explorer, and then do a multi-selection in the Explorer right after. For now, you should be able to avoid this by reclicking that viewport instance in the Explorer or deselecting and reselecting it before doing the multi-select.
Working on a fix for this edge case, but unfortunately it won’t make it in for the next release. I’ll update you once it’s out though.
The fix for any other cases should be working now, so definitely let me know if you still run into this outside of the case above, since that would probably need further investigating and a different fix.
