Hello,
I am using 3.2.4 (I’m not sure if the bug happens more frequently because of the last update or because I reset my Saved folder recently).
I try recurrently exporting the Editor Preferences, but there is an engine bug I think, because the file’s never exported.
Are your other team members also using the ASC plugin?
Yes, but mostly, I am the one editing the BP code, and it happens several times by work session.
To the point I fear adding new nodes to comments and certainly not pressing ctrl+R 
In your settings, what is the “Cache Save Method” set to (defaults to Package Meta Data)?
I use Package Meta Data.
Thanks for your help.
Edit: I tried switching to File > Plugin, but the issue still occurs.
