Hi everyone
@Sparrow brought my attention that upgrading Stroll to 5.3.1 causes problems. I reproduced the problem when trying to upgrade the empty version of Stroll online. It was at 5.2.5, so kind of behind. To see what happens, download Stroll — A Roam-like experience in a free, downloadable file, then pass it through the process at https://tiddlywiki.com/upgrade.html. Then open the resulting upgrade.html. A bunch of things messed up.
Any idea what might be causing this? The warning talked about a core module about to be overwritten. So I went through the process again, and unchecked $:/core/modules/filters/has.js. But I got the same result.
