Your level did what it was supposed to do.
I to have V105 installed.
I also got rid of the landing at the top of the stairs so that the enemy would fall down when it got to the top of the stairs. It did not fall. It got stuck even though there was no floor there to get stuck on. It seems as though it is getting stuck on the top stair.
Edit 12:30 PM 4/19/2007:
I reinstalled V105RC2 and now the enemies walk up the stairs and dont get stuck at the top. Issue resolved.
Hold the phone! Issue not totally resolved.
I added a plaform at the top of the stairs and the enemy got stuck again. I took the platform awa and the enemy went straight up the stairs and over the top and fell to the floor. Not it seems to be the fact that the platforms are the issue.
I adjusted the FPS file so that the platform was below the top step and the enemy still got stuck.
I then removed the platform and the enemy still got stuck.
I tried using a ramp and got the same issue. The enemies dont seem to want to go from a slanted surface to a flat surface, or where a flat surface has been and then been deleted.
I removed the tallest section of ramp so that the enemy would walk off the end of the ramp. Just as I thought, the enemy walked right the end of the ramp. There had beem no flat segment there before. It only gets stuck where it goes from stairs or ramps to a flat surface or to where a flat surface had been.
This is getting pretty random and confusing. I will to bet that no one on the forums has ever seen this in this way and has no idea how to fix it.
We might get luck and have someone stumble onto this thread and have the answer. I have been wrong before.
