problems with arp on Virus TI

[ipomea]

it seems to me that there was already discussion about arpeggiator problems, but ill try to notice it again. I have Virus TI desktop version, and im using it mostly as VC in Ableton. some of my arpegio patches are unstable, i.e. through the song arp changes (most commonly it changes when midi file is relooped), then again returns on desirable state, although sometimes it plays with no errors.

can we expect it to be fixed?
or, can i do something to avoid it?

i have been experiencing it with all OS versions last few years.
