/savealias does not save the alias on the first try

[Former user]

I get the message "Saved. Use /tpto <alias> to return here in the <current world> world." I double checked under "Aliases" in the control panel but the alias does not appear, even after reloading the page. And no, &delete=<alias> was not in the url.

After a second try it finally saved the alias, and I could use /tpto and it appeared under "Aliases" in the control panel.

This has happened the two last times I've used /savealias.

I don't know how to replicate this issue except for just doing /savealias.

This is caused by the deletion and creation of aliases which end up removing newlines between each alias in the file
