Cloned worksheets and workbook

Hello everyone

I'm new in the forum, but I have been reading it already couple years I think. While working on improving my old project I run on weird error. After two years of working with this file all of the worksheets and workbooks got cloned in weird way which is showed only in VBA editor. I cannot delete them, cannot view them, but they cause series of errors in all of the VBA code (including Automation Error). Obvious precautions were made, and worked up till recent days. Screenshots of the issue below (Sorry for Polish language inside of it):

I cannot attache file itself because of all the fragile data that is in it. If it's needed let me know what other data I can provide.

Cheers

Hi Adeophan,
How they got cloned might remain a mystery, or might be due to a recent mistaken addition or modification to your code in the wb somewhere... (I once added code intended for one ws in another, and when the other ws misbehaved I went crazy because "I had Not modified it.") :D
but...
Could they be hidden? Right click any ws tab and click Unhide...
HTH
Cheers

Hi Alphonse68,
I tried to unhide them even before starting this thread. As you can see in VBA Editor, they have different icons so they are not standard ws or wb. At the same time I cannot use VBA to delete them, I receive ActiveX error saying that those names don't exist.
The whole problem is that I didn't modify VBA on this file for like 6 months, only sheets inside changed, but this should not interfere with code due to all of it being used based on Sheet names not their positions. I'm 100% positive that user modification of one of the sheets caused this mess, but due to large amounts of data processed each day I cannot afford to revert it to the old version.

To be honest I hoped that somebody already saw something like that and would manage to at least give me insight where to start.

Cheers

Hi !

Workbook is corrupted, damaged, …

At least perform a Web search on this subject !
Without any backup, just try to copy data to a brand new workbook …
