I have not been able to reproduce the Quad incident. But they can still travel on Mesa, and so can Suspensor crafts.
Thank you for pointing this out several times. This is on the list of items to be fixed.
I should point out that all of the current issues to be fixed, are kept in a spreadsheet. You can find the latest spreadsheet at this post. Please note the date on that post; clearly anything which has been reported after that date will not be in the sheet yet. I put updated spreadsheets onto that thread, and there is more detailed discussion about what is coming up in future patches.
I can think of one very reasonable mistake the AI would make, like I am quite certain it could do in FfH if you haste one of their units for one turn; they give "go to" orders with the info that the unit moves faster than it actually will once the promo fades.
That seems possible. However, if the unit is "going to" any location inside cultural borders, the computation will be correct. This miscalculation only occurs if it is going outside cultural borders. When you see the units leaving cities to attack, are the target stacks inside cultural borders or outside? The behavior we want is something like spearmen city defenders in vanilla. They will go on roads one plot away to attack, so they can move back into the city before the end of the turn. This is what "should" happen with quads; they should be city defenders who can go 1-2 plots outside the city to attack, and then get back inside the city before the end of the turn.
