The reproduction step is to drag a bandage with a mouse.
Search for the “FIXME” code within that place to get more information.
Expected behavior
The common way to bypass the Highlight instances limit is to have one model with a Highlight instance and parent models/parts under it.
However, this no longer functions as expected.
I expect that the Highlight effect will appear after setting the Parent property of a model to that container.
While playing around to find a “hacky” solution, I found out that modyfing any visuals-responsible property fixes broken behavior.
I suspect this might be related to some kind of cache optimization similar to the one present in Surface/BillboardGuis, however the “RenderCacheOptimizations” property of the Workspace is disabled.
