Thanks! I've added the updated model on Github."reload7" and "reload8" are also missing, which will respectively break "A Family Story" (FreePlay quest specifically for José Joaquím Almeida) and "Devlin Opera".
Unzip this and put it into "RESOURCE\MODELS\Locations\Town_Santiago\center". As far as I can tell, locator files are the same in Build 15 as in Build 14, so this should add the missing locators.
The tailor's shop is included in the Build 15 version of "PROGRAM\Locations\init\cuba.c", and changes to land locator files take effect next time you walk into the area. So if you have a savegame from before you tried to kidnap Edmundo, you should be able to continue from there.
