Wrong assignment of VST instrument with multiple instances

Hi,
I am typically using my preferred VST instruments several times in a project. I am using no Instrument tracks, but MIDI tracks to easily change VST-instruments and try other sounds.
It happened several times now in C14Pro that I save a project and after reopening 1 VST instance of a multiple used instrument is wrongly assigned to a MIDI track.
Yesterday I opened a project and instead of playing the Massive X bassline sound the project played a Massive X lead sound on the MIDI bass track.

The solution is easy: I have just to reassign the right instrument to the track.

Addition: sometimes I change the sound of a VST instrument without saving. I don’t think that this influences this behavior, but for info.

I am wondering if other users are facing the same behavi

Is your VST multi out or just unique instances?

I experienced this issue up to now with Massive X and Pigments with several unique instances. Audio out is only stereo used.

I use the multi outs of Halion. Never any issues.
I do use multiple instances of Reason VST but never have an issue with them.
Sorry, I’m no help…
