Hi. Ill try this properly this time.
Fault:
In current project 10 audio lanes with events (or without, this crash is very repeatable)
Import tracks from project
Select cpr (for test i have a project with 10 tracks, no plugins. just faders set creating a wave to prove successful import)
“Track data to be imported” is set to “channel and inspector settings” only
Select the 10 source tracks and then select their destination into the current project respectively.
Click ok then ====>>>CRASH
A serious problem has occurred…blah blah… save your track under a new name…(by this time is already buggered so…no)
click ok to continue
all the tracks selected for import are gone except the first.
I have the same issue on 12.0.60. Trying to import everything except events and parts from a newer version into an older backup.
(you may wonder why I would do this: along the way I noticed that non-permanent Spectralayers data was lost from the project, so I need to go back but would like to rescue my work on FX and plugins since then)
