I couldn’t find either of these issues on github. Reporting bugs on the forum is great and all, but if it’s not on Github it’s probably not as likely to get addressed. There’s also a priority to things. I imagine blobs splitting through obstacles is pretty low on the list of things that need done.
I’m not familiar with either of these issues, but if they’re legitimate, I’d recommend you open them as issues on the Github, that will give you the best chance of having them addressed.
