I can supply the GDB, but the file is too big to send it through this website. Do you have an email address where I could send you a link to the data via Dropbox? Thanks!

The dropbox link has been sent.

Please note, I create groups in the 'Layers' panel of QGIS such as "App A GDB", "App B GDB", "Oak Hill GDB", etc. Then I add the layers from the GDB under the appropriate group. Then I usually shorten the name of the layer via the 'Settings' page of the 'Layer Properties' window so that I can see the name of the layer in the 'Layers' panel
(i.e., QGIS adds the layer as "Update_Current_09192018 Appalachian_Forest_A_Ownership", but I change it to "App A Ownership").

I may open the same project for many days before it ever glitches on me, but eventually, it glitches.

Hope this helps!

can you provide the project file then?

well... I can try for a few minutes...

I can't trigger the problem with just only the data, maybe the project is also important, better share it too.

The project was sent via the email address above. To use the project as is, download the GDB to your desktop and change the name of the folder to "Update_Current.gdb". There are several of the layers in the project that you will not have though because I use several topo layers and aerial imagery and other layers that are stored in several different places on my computer. I only remember having issues with GDB layers. I do not remember ever having this issue with any other files types that I import as layers. I don't know how to trigger it. One day I open the project and there it is. It may be one layer or multiple layers, but I do not remember it ever being all of the layers from the GDB. If I remember correctly, I have only had the issue about twice since I upgraded to QGIS 3 in February or March 2018. If it ever happens again, I will try to see if I can send you the project with the bad reference layer before I correct it. Unfortunately, I have already corrected the corrupt layer in the attached project by removing it and adding the layer again. When I was having the issue in QGIS 2.8 I would correct it, but eventually, it would happen again.

Douglas, did you add the layers using the Browser panel or using the Data Source Manager?

It seems that using the Data Source Manager, a layer from an Esri Filegeodatabase is added by layername as

path\filegdbname.gdb|layername=Layer_name

Using the Browser panel, the same layer is added by layerid like

path\filegdbname.gdb|layerid=2

Adding layers by layerid is bad because it leads to this kind of "layer mixup" in QGIS projects (see also #16135 and #18081#note-8).

The Browser panel incorrect behaviour should be fixed.

Anyway, if the layers source string are saved in the project by |layerid= instead of by |layername=, fixing the code will not fix your project. You should re add again the layers (or change the datasource programmatically) ensuring that the |layername= is present instead of |layerid=.

I think the problem was fixed in QGIS 3, but I used an old project from QGIS 2 as a base project that likely had the old file path instead of the new file path. It appears I may have wasted your time, but maybe not if it will help others not to load files through the Browser Panel. Also, any old projects created in former versions of QGIS may need attention to change any GDB file paths to "layername" instead of "layerid". I have many projects that are likely to be used again that I created in QGIS 2. I will be aware of this in the future. Thanks again for all the help!!!
