Okay, so after a day of experimenting, it seems rdb’s detach and flagging of it’s container as “None” works for me when modified with removeNode() instead of detach, using “render.analyze()” I was able to check and compare the number of nodes and this method seems to get rid of all but one.
Maybe that node can be found later, but sadly, I did try clear() method, and it made things much worse in fact, it did not wash away the nodes and piled them up doubling the node count and the strange crashing glitch from this thread
Has reappeared from it, anyway this solution seems to work, though I get some slow down some time after the cleanup is done, which scares living heck out of me as it was a prelude to the said glitch in the above thread.
But so far it seems to be working for the time being, thank you rdb, your information seems to be enough to answer my question.
