Just had a weird issue with AutoCAD 2017. I used Ctrl+C (copy) and Ctrl+V (paste) many times to copy objects to different locations. Eventually and randomly during the process my objects started pasting as blocks with random names. The issue was annoying, I looked for solutions and it brought me to this thread that mentions the use of the regular COPY command. The regular COPY command still caused my objects to turn into blocks with random names. ....
If regular COPY is turning them into Blocks, something's really wacky. How are you invoking it? If you start typing the command name, and it goes into auto-fill, are you sure you're "getting" the right command, and it's not [for instance] defaulting to COPYCLIP as you pick or hit Enter or something?
As to the wacky names, people may be interested in this routine, which redefines the PASTEBLOCK command, so that [whether invoked with the command name, or a menu item, or Ctrl+Shift+V] it requires you to give the Block a meaningful name. If you have that in place, at least you'll be able to tell when "eventually" starts, by the alert box that comes up to ask for a Block name, and you can cancel that. Then investigate what you've done most recently that may have changed something about how COPY works.
