Hey @Basstor,
If you’d like me to take a quick look at your Log Package in the meantime, upload it to Google Drive and send me the link via DM. Please don’t post the link here in the thread.
Regarding the Canvases: since this comes down to how Canvases are versioned in 3.2, I can’t promise a new beta that changes this by Saturday.
Do you have a copy of your project, or of its Canvases folder, from before you opened it with the beta? If so, those Canvases should still open in 3.1.4, so you wouldn’t need to rebuild them from scratch.
I’m looking forward to your reply!
