There are some formations that appear under my 'Custom Formations' tab of the free roam spawn menu, despite being deleted from the formation designer. As a test I deleted every formation from the formation designer: But in the free roam spawn menu they still appear: The UGCFormations_0.sav file is not empty either. It can be solved by just deleting UGCFormations_0.sav, but if one has a lot of formations to remake this isn't ideal. One way to replicate something similar is to save a formation, close the game, move the .pak file that contains the trains you used in the formation out of the DLC folder, then start the game again. The formation will no longer show up in formation designer and therefore cannot be deleted until you move the .pak file back. A way to delete these invalid formations would be nice, for example maybe they could show up as greyed out and disabled, but allow you to delete them.
