Hey, the patch I am currently working on has errors with previews > 2021.4.11-1053.
So I guess they are caused by these changes by @Elias
When starting the patch it throws an Object reference not set to an instance of an object error which doesn’t happen with older versions. When restarting with F9 the patch runs but the graphics output doesn’t look correct. Changing the patch, for example adding an IO-box results in an error again.
Idk if this is the cause but the patches/documents have cyclic dependencies.
I can’t reproduce the issue with a simpler patch and can’t share the project publicly, but get in touch with me or @tonfilm and we can give you access.
