Hello, I have the same problem. I understand that I need to call the BigWorld.wg_collideSegment function inside of BigWorld.callback(...) but I have a global function called "run_all" that runs the entire mod, why can't I simply put run_all in the BigWorld.callback() ? I tried and it does not change anything (wot client does not respond after some calls). I'm doing this because I want the collidesegment call to be synchronised (wait for it)
