Flow elements "disappear" when PsychoPy is closed

Hi all,

Been using PsychoPy (in Builder) for a few months now and never come across this issue. I have a task that I finished creating this week. But suddenly, when I open it, all the flow elements have disappeared. They haven’t been completely removed as the associated tabs are still open. I keep repeatedly having to put them back in place and even then my task won’t work anymore.

Here’s what it looks like when I open:

I can’t figure out what could have happened. I woke up this morning and it’s suddenly not working. I’ve tried uninstalling and reinstalling PsychoPy which didn’t help.

I really would appreciate some advice as I was hoping to start testing participants with this script next week.

You don’t say what version of PsychoPy you are using, but there was a bug in an older version where renaming a static period component would cause problems with corrupting the file. It is likely that the information is still within your .psyexp file but that reference has gotten corrupted somehow.

You probably need to post your .psyexp file here: it might be able to be manually edited to restore it to health. Also please let us know what PsychoPy version you are using.
