I installed the new smap_test files yesterday and spent the evening on a new Shimazu campaign. Initial observations in no particular order:

* training ships from Hyuga, and they come out in the right sea area (ie the one with the port in)
* starting armies look ok
* Japanese teppo still get their honour bonus in a province where they can't be trained (Awaji -- no iron -- no yoroi -- no JT)
* still need to turn down the volume on generals/heroes - just a few years into the campaign I have six provinces and every one has a general of at least 7* in it. Leaves no room for development. Maybe keep Daimyos down to 5* max. at beginning of campaign
* probably not MOD related, but just in case: I have a hero with "expert siege defender" virtue (+3 years to siege duration) but this doesn't work. Putting him in garrison doesn't improve the likely years to hold out, and when I let him get besieged the castle was "likely to hold out only 1 year" (I was counting on those extra years to train up a counter-attack army)
* rebellions: seem to consist almost entirely of huge stacks of yari cav (but that's okay, it wasn't MY province that rebelled )

That's all I can recall for now, cheers
