Hi.
I’m working only with MED files and I don’t know if this applies to any other format. If I want to reload a file, using reload function, I’m loosing possibility to see results in vewport. All data is present in pipeline browser, but I can’t see anything in 3D. The only way I found to deal with the problem is deleting all the work from pipeline and manually reopen the file.
The same thing happened in v5.12

Hi @K_Zurawski
This sounds like a bug in the MEDReaderPlugin, however this plugin is maintained by the salome/paravis team, you may want to reach out to them.

Just wanted to add error message in case this is not MEDReaderPlugin error:

This means it is coming from the MEDReader plugin.
