This is a non-exhaustive list of known issues in the RAS 2025 Alpha. We will remove items as they get fixed, so keep an eye on the Release Notes page ... We generally will only put bug reports here if we are able to reproduce the issue internally, For example we will not use this page to document missing or partially completed features.
Major Issues
Major issues are any that may cause crashes, data loss, or strong disruptions to workflow.

Generated Mesh incompatible with RAS 6.6 (too many cells around a facepoint)
In RAS 6.6, there is a limit of 8 cells around a single facepoint/node. The RAS 2025 mesh generator can create meshes that exceed this limit.
Can't use 2025 mesh in v6
Massage mesh to improve mesh quality in those areas.
Wait for RAS 6.7
This limit has been lifted for RAS 6.7 Beta 5
We're looking to reduce the number of situations where 2025 can create meshes with this issue.
Minor Issues
Minor issues are generally UI errors and annoyances, or issues with simple workarounds.

Notes
Updater/Installation cannot copy files
When updating RAS, the installer may warn about issues copying files. The installer may partially succeed, leaving the installation in a corrupted state.
Prevents updating, may corrupt installation
Try to kill the process Ras.Interface.WinUI.exe
Restart computer
We've noticed a few crashes that occur deep in the Windows UI stack that can cause zombie processes to hang around, particularly when 3rd party anti-virus software is on the machine. We're continuing to investigate this and will update with known workarounds or fixes.
Instability running from network drives
When running RAS from a non-rooted drive (e.g. \\share\path), various disk functions do not work correctly. We're working to address this.
Disk load/store corruption
Install RAS in a rooted drive, e.g. under C:\
Instability running as Administrator
When running RAS as an elevated user (administrator), some operating-system interactions (like opening a file dialog) will cause the software to crash.
Crash
Launch as a non-elevated user.
Instability running with Unicode characters in Path
When running a RAS project with Unicode characters in the path (e.g. "Ö"), our underlying file storage system (HDF5) does not handle it well. We're investigating workarounds.
