How/when does this happen:
Only happened once so far, not sure what actually caused it. Myself and the one other player online didn't notice any symptoms in-game, but I figured I'd report it just in case it's something critical with 1.20.1 support.
Other information:
The Purpur build is custom compiled with an additional pull request that hasn't been merged yet by the Paper devs.
