When you have a sec, try running only RTB with a default install of Blockland and see if it causes problems.
There seems to be some bullstuff Blockland OSX bug causing lots of issues which I don't think Badspot can debug easily. It seems to be related to the number of tcp objects being used. Blockland has a fair few by default, RTB adds more and that just seems to exacerbate a pre-existing issue.
Tl;dr not my fault
