Various ConcurrentModificationExceptions when naming params

Happened when I tried to name a param.

Moving this from #243

Initially I had them separate because when I compared them they had a different stack trace.
I've since noticed that #243 has several stack traces, and one of them is the same as the original stack trace for this issue.

After restarting Enigma, I named a few without issue, then it started happening again for each rename.

It works fine if I click retry.

Sometimes it dismisses the error on its own (auto-retries?).
