r469 makes my game unloadable

I have a very large project, DinoSystem, it's on Steam Early Access.

Construct 3 r469 makes the game unloadable, meaning each time I save it, and then load it (doesn't matter if I create the game with r469 or a previous version) the save is totally messed up, with very weird things happening (hierarchies broken, effects over the top, and so on).

I know I should write a report with a minimal project, but I simply can't due to the sheer complexity of the game and my cluessness about what could be causing it: the only certainity i have is that r469 caused it.

As I load a game, the console shows this:

I assume it has to do with the recently added changable sampling mode?

I need more info to create a proper report, so any help is appreciated!

I also get this on my main project and the project is huge so haven't got around to tearing it apart.

My suspicion is using dynamic layers to add layers during runtime, maybe it was an oversight when adding the new sampling modes per layer - Do you use dynamic layers in your project, too? If not, I am also clueless!

Someone else also reported it but also did not have a repro, so it was closed: github.com/Scirra/Construct-bugs/issues/8918
