Hi Xanadron,
We have had several people create ledge pull up and full climbing systems without running into this issue; which makes me think this probably isn’t a bug.
Here is some more info on a couple of those systems I mentioned:

However, if you believe this is a bug, could you provide some more info? A small test project that showcases the bug would be preferred,
Thanks,
