I've Never Counted This Many Errors On A Bill How Did This Get Make Circulation
As a general rule, the answer to this question is "it didn't". If you find "multiple errors" on a coin or note, 99.5% of the time, it's usually just one "error" or event that has caused all of the differences. Which is why I'm suspecting "solvent" for this note, as it would be a single "event" that can explain all the "wrong features". Occam's Razor says that if one event happening to a note is improbable, then having multiple improbable events happen to the same note simultaneously is extra-improbable. Not impossible, just really, really, really unlikely.
And, as another general rule: if you find "spectacular errors" on a well-circulated note, the chances are highest that those "errors" were not there while that note saw that heavy circulation - somebody else would have spotted it earlier and kept it, or somebody in a bank would have flagged it as "unfit for reissue" and destroyed it, long before it got to you.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
