urgh. its solved. i was using a too old A7. also time_step kinda malfunctioned when running a published script UNLESS the dubugging panel was open. hows THAT for an infuriating error, but it's cleared up now too.

i spose the jokes on me, being naive enough to think that they wouldnt release a GS in which such a central function as move wasnt working properly.

anyway c_move doesnt suck anymore and iv learned a lesson. so all good. i still heart 3dgs
