Selecting a model in a massive 20k instances model causes extreme minute long freeze.

I have to debug really large models frequently in my game and its really time consuming due to selecting a part or model causing a minute long freeze.

If this were to be solved it would massively improve my workflow.

Its strange to me how highlighting a single model under another model can cause roblox studio to freeze for this long.

The same lag spike appears when holding alt to select a specific part.

I think roblox uses O(n)-like algorithm inside. Try to convert all parts you can to Union.

Could you please include a program dump, reproduction information and your log files.
