Description: I use LibreOffice for school, as I type all assignments. This includes assignments with a large amount of math. In math-based assignments, I use the formula editor for mathematical symbols. I often will have a few hundred formulas in a single document. Recently, however, I have noticed that in some documents (it has happened on 2 so far), a large proportion of the formulas get deleted and replaced with "Object n" labels where n is some positive integer. Looking in the .odt file, I see that the folder for the deleted objects has vanished. On the most recent document, I was attempting to export it as a PDF immediately before the issue occurred. It said that there was a "General Input/Output Error," despite the fact that other processes under the same user account could create and edit files in the same directory as I was attempting to create a PDF. After I saw this error occurring, after multiple export attempts, I closed and re-opened the file to find my formulas missing. I have attached this document, after the error. Unfortunately, I do not have a copy of the document from before the error. In both of the documents in which the error occurred, I have images of mathematical expressions or equations from WxMaxima in the document. To embed these images, I selected the appropriate text in WxMaxima, right clicked, clicked copy as image and then CTRL+V'd it into LibreOffice. Steps to Reproduce: 1. Create a document 2. Add a bunch of formulas 3. Embed a WxMaxima formula a described above 4. Continue adding formulas 5. Open and close the document. It may or may not experience the issue. Actual Results: Formulas a missing Expected Results: Formulas are intact Reproducible: Sometimes User Profile Reset: No OpenGL enabled: Yes Additional Info: Linux: Arch Linux Linux Kernel: 4.18.16-arch1-1-ARCH CPU architecture: x86_64 OpenGL system: Nvidia proprietary drivers for GTX 1070m

After posting, I noticed that critical is an option for bug severity. As this can delete an arbitrary amount of work, I think critical is the most appropriate severity. I request that someone with permissions to change it to this setting does so.
It isn't a bug about formula editor, because you lost many images, that you pasted in to Writer document from wxMaxima. For checking of this bug we need primordial file, please make it and attach in to the bug And please add info from dialog Help->About

I did not lose the images that I pasted into LibreOffice from wxMaxima. I lost LibreOffice formulas in a document that *also* contained wxMaxima formula images. I do not have a copy of any files before the error occurred. I only have a copy of the files from after the error, unfortunately. If there is some way to predict this before it occurs, I can create such a backup. I have attached a screenshot of the about dialog.
Without source document and repeatable steps, cannot be confirmed. I guess safe enough to mark duplicate of another not confirmed bug. *** This bug has been marked as a duplicate of bug 119548 ***
