This is damn annoying, renders Tokamak useless unless you want to create everything at the start - why the hell don't they fix such an obvious fault?
I'm pretty sure that won't happen.
It seems Chris & co abandoned Tokamak a long while ago.
If you check the forums it's totally infested with spam.
I think someone recently wrote a blitz3d-wrapper for Newton.
If that one works I would totally recommend it instead.
