Does not work is no useful description. Macro does not exist? Keyboard shortcut broken? Seems to work, but result is not as expected? Or what else?

Not a valid bug report!

Sorry. I will try to be more precise. I recorded a simple macro to paste a block of data simply as number. Then I associate this macro to a new menu item.
All was working for a couple of months. After a program update, after clicking on the menu item, I received an error of macro not found (or something like that). The macro disappeared from the macro list.
I repeated the procedure creating a new macro. Same as above: after some time, I found that the macro disappeared again.
Unfortunately I have not recorded the error message. Next time I will do if the issue comes again. I am not sure that the issue is caused by program updates or something else. (sorry for my English, I am italian).

Unfortunately still all relevant information is missing, so I close this bug for now as DUP of "Bug 52022 - CONFIGURATION: 'My Macros' lost after update from 3.5.5.3".

I will soon do further tests there, because currently information there also is rather poor.

@vimot2:
There is no need to cite all comment. Please use Bugzilla frontend (not mail client) for your comments and only if necessary and only parts of former comments.

I only have experience with WIN but I believe on Linux it will be very similar. I use the default "Folder" "My Macros" in the User Profile
<https://wiki.documentfoundation.org/UserProfile#User_profile_location>
under .... \LibreOffice\3\user\basic\Standard\ in a file called "MyMacros.xba" (or similar). With a text editor you can see the source code.

Now the question is whether the .xba disappeared or has been destroyed or whether your profile folder changed or whatever?

You can get assistance on

or on the public users mailing list <users@libreoffice.org>, a mailing list from <http://www.documentfoundation.org/contribution/#lists> or

Please feel free to reopen this Bug if discussion with others leaded to an assessment that we have a LibO bug and a clear and comprehensible description of the problem due to  <http://wiki.documentfoundation.org/BugReport>.
