I've been creating a Counter Strike 1.6 map for a couple of weeks, essentially finished it and compiled.
The compile log looks nothing out of the usual, no errors or such noticed.
To the problem:
I attempt to launch the map, but it crashes showing me an error about me not having the models, that the map uses. You know,
Mod_NumForName: "place where model should be"/bigtree.mdl not found.

Normally one would think I don't have that model, but that's the problem - I do. Everything works fine if I remove the models. So what could be the problem?
