Looks like Adam patched it in the
WidgetOverlay API(whatever those notes say) and seems to be the only thing I can find with my limited knowledge since that API is spitting errors in IntelliJ. This ones open-sourced so you could try and bypass it but I'm not knowledgeable in coding whatsoever. I tried changing everything that said WidgetOverlay to WidgetOverlays but it didn't work as "WidgetOverlay.java" was replaced with "WidgetOverlays.java". Don't think that dev will update it or just keep his working one private like others to prevent patching. The paid ones that are mostly on here weren't affected or already updated with this change. Pretty sad since that one was the first actual public plugin after OpenOSRS shutdown that worked without paying $15+ monthly which is more than osrs membership.
