Does anything change if you use JSDoc to disable Feather for GMLive scripts? There’s reasonably a lot of code to it.
Viewing post in GMLive probably causes 2022.1.464 to crash
Russell wrote on forums that Tuesday (1st Feb) beta version will have tons of fixes for Feather, so I will wait with reports. Generally IMO best solution would be to mark most of GMLive scripts and variables as ignored, as they don’t need to be exposed (except those that are documented, like live_call() etc.), so that requires YYG to make those features stable enough to start thinking about it (as some things are bugs yet, but are not completed at all).
