Starting a new project after having loaded a WAD with both maps and resources seems to keep references to those resources despite not being loaded

There seems to be a bug where after having loaded a large WAD project (including textures and flats), and then starting a new project (with just a simple map, and the initial default layout) would still keep the resources from the large project in memory, despite no longer being part of the current map's project. The textures would go away as soon as you go to Manage Project and click OK.
