This happens because actor viewer is initialized when the object tab is opened, and one of the things it does is create a blank terrain. The terrain references a texture from the global terrain texture manager g_TexMan. When a new map is loaded, those textures are unloaded and reloaded again, causing actor viewer's terrain to hold a bunch of invalid pointers (or randomly, valid pointers to the wrong textures).

Note: See TracTickets for help on using tickets.
