At least one got left in (found during beta testing), because they ran out of time due to the anniversary.
Bug Details:
Randomization bug (ALL EFECTS):
If an effect is loaded into FX1/2 on any audio track of an unsaved PART and the user randomizes (FX1/2+YES) the effect page, then undoes it (FX1/2+NO), the parameters will not be initialized.
