updateInvalidatedFastClusters/updateEntity triggers on character descendant part property changes, causing spikes

[Ax1sAng1e (Pastor James)]

Pretty much the same bug here, not sure why this was marked as Fixed.

Layered clothing causes lag spikes when updating unrelated part properties

We understand the source of the lags and have an improvement for that in progress, but we had not seen reports of a memory leak before this. They may be two seperate bugs, or it may be an issue specific to your setup. Do you have a simple test place you can share?
