Carla Rack don't restored VST's on Qtractor

[wakoo]

Hi. I've worked with Qtractor and Carla-Rack (LV2) for load win-VST (.dll). Plugins load very well, instruments and effects; but when I re-open the session of Qtractor, the plugins that I've load on Carla-Rack don't restore. On Ardour I used carla-rack for virtual instruments (win plugins) and all were restored after re-loading. Does anyone else have the same problem?

Maybe it's the same problem as with some LV2 plugins.
There was a known problem with some Carla versions.
It didn't happen in version from 2018-08-21 and earlier. It's fixed now.

Well, I updated Carla git (2:1.9.13+git20190117v5) from KXStudio repositories and all related packages. I've noticed that problem occurs when mix multiple plugins or something, for example: First Track (from top to bottom): Ob-xd + Carla Rack LV2 (load a overdrive vst) + vopa. Then, when re-open the Qtractor session load very slow and bum all Carla Rack instances are empty I've tried with a new session with only Carla Rack instances and save plugins and changes, but when I start to work and add changes all turns to a big disaster: re-open session and Carla Rack are empty.
Sad news.
