Construct Animate r398.2

Notes

Introducing major new features means integrating a lot of new code, which can be a tricky process that ends up causing issues itself. The build for the previous release accidentally introduced some crashes when using the new Instance Bar, and as that makes it hard to use at all, we're releasing this patch update to correct it. Hopefully this allows more testing of the new feature!
