Hot reloading issues with 4.16

Currently getting this when trying to compile:

Works after I close and reopen the editor, so seems to be a hot reload issue. Is this a known issue or something new I’ve come across? It’s happened to me a few times today now.

Cool, thanks for the update.

Hi,

The fix for this will most likely be in the upcoming 4.16.2 patch release.

Sorry for the trouble,

Steve
