Hey everyone, sorry for bumping an older thread here, but if you're experiencing this, could you contribute to this issue: https://issues.frontierstore.net/issue-detail/34099
We'd love for you to add the system / planets you have noticed the invisi-rocks too, but appreciate it may have been a while!
I've encountered those - seemed to me to be more prevalent on Icy Worlds. Unfortunately I haven't taken a note of the ones I did encounter, but I'll go searching for more icy planets and have a bit of a drive around in search of those invisible nemeses.
