I am trying to figure out where I have cp invested.  The game says I have 15 cp used for houses.  I have 8 in a Residence in Grana and 3 in a residence Heidel.  That leaves me 4 which must be being used in a workshop or storage or something else that uses cp somehwhere and I have no idea where?

Have not been playing that long but hard to believe there is not any sort of CP management tool or something like the Residence button that tells youwhere they are so you can get your cp back fro them..  If there is I cannot find it.

EDIT:  I managed to locate 2 of the 3 cp.  2 were being used as storage in Stonetail Horse Ranch.  I tried to sell the back but was told that storage was ful and had to visit a couple places and finally removed enough items from Altinova storage to allow me to see the houses back.  Now I just have one more house that I need to locate somehow.  What a pain this has been.  I have no idea how you people that use 100s of cp keep track of there they are all being used.  Residences, workshops, storage, containers, fences, nodes and who knows where else...

Unfortunately, they have not implemented a simplified way of finding where you have your CP invested. You will have to do it manually. For cities/towns, you can click the button to see the Purchased buildings. Then you can check nodes where you may have had workers or invested into for node drop rate.

you can save a little time searching by looking at the hover tip for the city/town w/e, there's a (x / y) number above each one when you mouse over... that's the number of buildings you have invested in for that location... then if it's not (0 / y) click on the town and do as NightMare suggested
