[chimerax-users] Error in reopening session

[Maximiliane Wieland]

Hi,

When I try reopening a session I have been using for two weeks now (so many saved view :( )and I get the following error:

Unable to restore session, resetting.

Traceback (most recent call last):
File "/Applications/ChimeraX_Daily.app/Contents/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/chimerax/core/session.py", line 653, in restore
obj = sm.restore_snapshot(self, data)
File "/Applications/ChimeraX_Daily.app/Contents/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/chimerax/basic_actions/statemgr.py", line 65, in restore_snapshot
cmd.name_frozen(session, name, Objects(**value))
File "/Applications/ChimeraX_Daily.app/Contents/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/chimerax/basic_actions/cmd.py", line 54, in name_frozen
raise UserError("nothing is selected by specifier")
chimerax.core.errors.UserError: nothing is selected by specifier


This is the error from the daily build, in the production release one I get the same error, only difference is in "cmd.py", line 52, in name_frozen
When trying to open an older version (that I saved but did not open, since I kept using the same session and saved it to the latest version) I am asked to replace missing files, which are in fact not missing but still in the very same directory and with the very same
name, so it feels like the real error lies elsewhere? Can I make it reopen the session without reopening the volume? 
The last version of the session I can open without a problem is close to two weeks old, I named some selections in the meantime, could that cause such an error? 
I use ChimeraX on MacOS X 10.12.6
I will also submit the bug but since it is kind of urgent I thought I would try submitting here, too, in hopes of a quick response.

Best,
Maxi
