It is triggered by publishing an animation twice prompted by this code:
local function publishKFS(keyFrameSequence: KeyframeSequence)
Selection:Set({ keyFrameSequence })
local plugin = plugin or getfenv().PluginManager():CreatePlugin()
plugin:SaveSelectedToRoblox()
end
Also forgot to mention - this issue is reproduceable on both the traditional Roblox studio UI, and the new UI beta - likely because it’s an error with the asset upload UI which is unchanged in the beta. Let me know if there’s anything else I can provide. Thank you!
