New beta cycle: Nested timelines & lots more!
I just tried it and it worked fine. Please do file an issue, because we usually need much more information than this to solve problems, and it also avoids the problem being lost and forgotten.
Oh yeah weird, it's working now. I guess it is more obscure than that. It was on an empty project though. If I manage to replicate it again I'll file a bug report, thanks Ashley!
