Comment 3 for bug 1447831

This route also has problems with 'spurious world files' - world files which reference track sections and signals etc. which are not included in the tdb.
These world files are part of an abandoned extention, but the references to signals will corrupt the OR signal database.

This is what needs to be removed :

If you delete the 24 world files that are part of the abandoned Oshawa area, GTA will run fine.
The world files you delete start at "w-011199+014529.W to "w-011211+014523".
