Yes, that is possible. Seems like I reported this much earlier in this thread, and Sour quickly fixed this in a newer version of Mesen.
Are you running an older copy of Mesen? My version is DevWin-0.9.9.62 and .cdl files stay forever.
Note: Any of the DevWin versions aren’t available to dl anymore bc Sour’s site, the one where DevWin versions were available, removed those DevWin files after half-a-year. So, I recommend you obtain mkwong98’s version he listed at the top of page 66.
