Hi, You may still be puzzled by why some TRS2010 and earlier builtins don't show as builtins in TS12. Legacy builtins, other than those being used specifically for TS12 routes and sessions and any add-ons like Murchison 2 or DLCs like Blue Comet, were purged from the builtin files and placed on the DLS. As any of these previous builtins were masked they would not have shown errors while they were builtin unless opened for edit, but now that they are non-builtin their true error status is revealed as soon as you download from DLS. You should also note that if viewing assets in various Trainz versions and comparing the results, they will differ because validation is trainz-build related.
