Prestashop multistore and importing

[fritzelly]

Am I just being stupid?

I already had a store set up for one website

Went to add another store for another site for something completely different and after 3 days have given up and just installed a separate instance

Importing categories is totally random, they may end up in your shop, may end up in the other shop, may end up in cyber space even tho they are in the database

Even when the categories do get imported the relationship (sub categories etc) is completely ignored as is the shop ID assignment (they just seem to get assigned to all shops even if you can see them at the end)

I have tried every variation of importing stuff and am now bald

Everything works great for a single store

From what I can surmise in a multi store the shop id has no effect and using something like cat1/cat2/cat3 has no effect as every category is created as a separate instance (tried importing categories first and then products - all that happened is all the categories disappeared from the shop and some random category became root!) and god knows where the products are assigned to
