uh... hubs go on the intersection of two lines? the only way to get two lines to intersect.. the only way whatsoever is to make an x pattern with two lines. and right clicking that intersection does absolutely nothing.
oh my christ. i refreshed and made three train tracks and added trains to them until i have 6 trains and that didn't trip the "have 5 trains" requirement for hubs.
i'm sorry but this is impressively bad. nothing about it makes sense or is fun or playable whatsoever.
kids should not be allowed to vibe code with LLM's.
