Bug: Images inserted in Research texts disappeared with update

I use image files in my research texts. Sometime during the last couple of updates, these images have disappeared. These were text entries inside a folder.
Further, the text files (Is this what you call them? They’re not converted into folders) seemed frozen. I couldn’t type in new information. Some of these files also carried an custom icon, but not all.

This happened again with the latest update.

Just noticed this also.

Can you please share some more details about this problem. Probably screenshots before and after the update pointing at the missing files. The update installer does not interfere with your projects and the file format is stable for a long time, so there is no good explanation about the loss of project image files. Please, also share the location of you projects on the HDD.
