I have a managed package in which I have a few flexiPages (Lightning App Builder pages) I have an object Project__c (this is the default page) on which I have configured tabs (in Lightning App Builder) these tabs take you to different VF pages.
My package is currently on version 1.20. I installed the beta version for testing purpose and I noticed the tabs are missing and the URL for that page is incorrect. The correct URL is https://my-beta.lightning.force.com/lightning/r/NAMESPACE__Project__c/RECORDID/view
But Salesforce has generated the following URL https://my-beta.lightning.force.com/lightning/r/NAMESPACE__SOMEOTHEROBJECT__c/RECORDID/view While its still on the Project__c record
The RECORDID in the incorrect URL is still the Project object's.
None of the previous builds have faced this issue and I haven't updated these pages in a while. I have only stumbled upon this issue twice now and I don't know how exactly it can be replicated. The only thing that might have caused this to happen is the Winter 19' release? I've been through the documentation and haven't found anything so far.
What should I do next? Please let me know if something isn't clear.
