Yes,this could well be the case.If the segments are not exactly 100 units,then a thing called null space will exist.The way FPSC handles AI is it moves them on a grid and if there are empty spaces on that grid,then the AI will jump up/down chaotically.
When I buy DarkAI I will start making my own mod and hopefully be able to replace the whole AI movement system /end self-advert./
I would recommend you use DarkAI instead of the regular AI scripts and instead of the maintenance segments,use plain segments with fitting textures of your choice and make some edges(handles) with static entities.DarkAI will automatically avoid static entities,unlike the regular AI system.
