Insync randomly started to delete stuff

Hi, as per the title, today insync started to delete stuff randomly, without any change to the directories.
Up to now, Google Drive reports ~ 1’000 files deleted. The files were only deleted from the online account, while they were still in the local directories (I think, I’ve not checked all the huge list).
So, after Insync show no other progress, I decided to quit it and restore all the files directly from Drive. Then I restarted Insync again and again it deleted all the files. After this, it started to do a huge upload of ~8’000 files.

What’s going on there? Is it due to the recent upgrade?

$>insync -v

>uname -r

$>lsb_release -d
