When parsing .sln files solution, folders are added to the model temporarily and then reparented. If there were multiple folders with the same name they would generate the same initial default id. When the actual id was assigned, it would remove the original one from the solutionItemsById lookup table, even if it was for a different folder. This would result in an error saving the file.
In addition, when the folders were reparented the default id state needed to be reevaluated.
