Some AMFP Assets Not Appearing

[AGP]

All righty, I started working on a mod with some AMFP assets and some of them work and some of them show up in-game completely invisible.

I read on another thread that some of these assets would move to other locations in the map, so I moved this particular assets (fan_ceiling_short.ent) down to see if it would appear.

Lo and behold, it did not show up, BUT when I walked into the space it was supposed to occupy, the player ran into something invisible: meaning, object is there, texture is not.

I read through some other posts mentioning this issue, however I could not understand much past opening the DAE and ENT files in Notepad and something about .mat files.

In short, do I replace the textures so that I might see this beautiful fan? And please, explain this to me like I'm a complete noob (which I sort of am for the most part).

EDIT:
I went back into the Amnesia game to look over everything, and wouldn't you know, I found the fan! It's sideways, stuck in the floor, and I can walk right through it.

Seems the question I must really be asking is how do I bring this fan's body and soul together again?
