Please read this changelog, it's important. It contains all the changes related to this plugin and also things you could have to do after updating. If there's a GCore update, you have to download it too.
I mainly provide support on my Discord server (the link is on the plugin page). Thanks for reporting bugs and suggesting features. Consider leaving a nice review to the plugin if you're satisfied with my work and dedication ! <3
For QuestCreator v5.12.1 :
Fixed :
(#233) An error being thrown when a structure grew.
Command '/qc menu' couldn't be performed from console.
(#236) Conditions type selection in the in-game editor would create infinite GUIs with the old condition type.
(#235) Condition error messages wouldn't be sent in a CONDITIONS object even though there was a fail goto.
