From what I see the latest stable release is 336. Maybe use that one instead of beta versions, beta versions will introduce new bugs.

well i always use newest relases because of bug fixes, animation editor still freezes or crasher in beta / stable version thats why im scared
but i dont want text here about bugs, Ashley should test his relases first
I must back to previous versions because last bug for 'AND / OR block' delete my events, i already have few crashes and few freezes animation editorper day without posibility to save my progress
So please.... patch and fix all bugs first, then add new features / examples/ customs actions
