Bug with FM on subs -- phase wonkiness

Ran into this bug a while ago but just got around to recording video on it. When you load up sub oscillator on default settings, have it play contiguous midi notes (there have to be touching one another end to end), and then crank the fm (in feedback mode on the sub) you can get it into a state where the phase is inconsistent between notes. Some weirdness I ran into this bug:

1.) Doesn’t matter how many voices the synth has, seems to happen in polyphonic and monophonic mode
2.) There doesn’t seem to be an obvious threshold where the fm knob starts making this happen.
3.) The only way to reset it seems to be loading a new instance of current and deleting the old one — deactivating current and reactivating it wont break it out of this behavior.

Slight loudness warning on the video for when i crank the fm.
