When importing the "lost-empire" obj file, the importer returns with the error message:
invalid vector<T> subscript.
I've tried to narrow the error location down and found out that it occurs in the file ObjFileImporter.cpp in the function createVertexArray.
The lost-empire.obj file can be downloaded from here:
