JOIN command doesn't behave like it used to in AutoCAD MEP 2022

[scott.mcgowanBRJVK]

When I type JOIN, instead of the lines I have selected becoming a single polyline like I have done hundreds of times in the past, I get a prompt asking to Select source object, which then does not join my lines together.  I then have to  use PEDIT to select Multiple lines, JOIN, Enter fuzz distance, and hit Enter. 

My question is : why does JOIN no longer work? All I can think of is something to do with the profile I'm using as I was fiddling with it and I'm not sure if I've changed a variable or system setting or something that messed up the way JOIN works.

I'm using Autocad MEP 2022

Hi @scott.mcgowanBRJVK,
Thank you for posting in the AutoCAD Forum! I hope the community will answer you soon. In the meantime, Can you upload the file or a screenshot of what you are trying to do,  so the community members can see it and help you better?

Thank you, and see you soon,

Hi Joaquim, I WOULD post the file/screenshot to show the issue, but after a restart, the problem seems to have fixed itself. Now after selecting several items to JOIN, I get the message "Select source object or multiple objects to join at once :"  which is exactly what I would expect the message to be. So in conclusion, the command is now working as normal. Something to do with me restarting, I'm sure, but what the specific change might be, I don't know.
