Hello there, I don't know what you made between v1088 and v1095 but now Mapsource works again very well (my map is based on Ireland OSM data). There is no more problem with tiles cache generation. Now I have to understand why a line's type with a value on two bytes (ex : 0x040c) in OSM file is changed in a type defined with the least significant byte only (ex : 0x0c) in IMG. Thank you for your great work, David
