InDesign 2020 v15.01 makes corrupt documents (linked to Alternate Layout?)
InDesign 2020 (v15.01) has a serious issue with making corrupt files. This is now rampant across several users and has become a nightmare.
What happens is:
At some point InDesign will give spinning beachball of death when opening the file, so it is not accessible anymore, or it might let you see the file for a minute or two before becoming unresponsive. Symptoms might also start with crashing on copy/paste, and then boom, corrupt document on open again. The document will then be totally inaccessable from InDesign 2020.
If I then use InDesign v2019 on a corrupt document to "Convert" it, it will usually be able to open in, sort of. It will however delete most of the paragraph styles and assign "Standard" to all text. So the document is a royal mess.
These are document templates we have been using for years. They have been used intensively with InDesign 2019 without problems. Version 2020 introduced the problem. We skipped version 15.0, waited until 15.01, so they have not been touched by 15.0
I think this is releated to either one or both of the following:
1) Fairly advanced Paragraph styles: using nested styles, grep styles and Character styles
2) Using "Create Alternate Layout" with using "Copy Text Styles to New Group"
Mac OS 10.14.6
Mac OS 10.13.6
Anyone else seen this? I really regret updating to 2020.
