Compiling error

[Kojak]

I get the following errors up on my console whentrying to run a test map:

maxplayers set to 1
Steam config directory: d:\steam\steamapps\kojak000\half-life 2 episode two\platform\config
Hud element 'CMapOverview' doesn't have an entry 'overview' in scripts/HudLayout.res
Unknown command "sv_backspeed"
CModelLoader::Map_IsValid: No such map 'maps/r.bsp'
map load failed: r not found or invalid

Note, my map is not named 'r', and I have failed to find anything fishy in the compiling log or the error report page at interlopers.net. I have tried compiling parts of the map, both through cut outs and by cordoning off areas, neither which do me any good. I have also tried to remove the (very few) prop_statics I've had, but that didn't help either. I'm not using any third party addons yet either, so what is actually wrong here?

Any help appreciated.
