Steam update (2nd June 21) corrupted files (2nd time this happened)

**Game mode:Online private
**Type of issue:Other
**Server type: PvE
**Mods?: Yes

The steam update from today corrupted some installation files. This is the 2nd time this happens and requires a huge re-download of files.
No other game whether Steam or not got such an issue. Why does this happen again for CE?

Hotfixes/Patches are not worth it if they break the client data.
