Hi
I'm not a fan of stancy's branding . Most reasons are lots of files/icons twice ,even three times
Anyway your issue is in pictures.icon
In old igo all files bmp and spr are in common folder so in files .icons you have : $poi_mapclose.spr
In primo all files bmp and spr are in résolution folder so in files .icons you must have : poi_mapclose.spr
In his primo branding Stancy go on with $poi_mapclose.spr ( all bmp and spr in common ) . No problem if all instrutions are coherent
But for 2.4 in ui_igo9/icons/poi Stancy added a file pictures.icon directly copied from data 2.4 so with instructions poi_mapclose.spr . no surprise Primo don't find poi_mapclose in résolution folder
So in pictures.icon you have just to replace poi_XXXX.spr by $poi_XXX.spr as you see in multipoi.icon
