Strange AI and Scenery error when "updating" the BSP

I'm just going to illustrate the problem at hand by copying an AIM conversation in here, it completely describes the problem:

L0dex: alright
L0dex: so the situation is as follows
L0dex: higuy had given me an unportaled bsp some time ago, which i had to populate and script etc
L0dex: i added some extra scenery to it, and the ai all worked fine
L0dex: now higuy gave me an updated bsp, which has been portaled
L0dex: after replacing the old bsp with the new one (and the corresponding lightmaps)
L0dex: the ai seems to be COMPLETELY invisible (except for gun effects), and they cannot die, nor does anything collide with the ai
L0dex: i also noticed that
L0dex: the extra scenery i had placed
L0dex: which should be completely disjoint with the BSPs
L0dex: this extra scenery
L0dex: is no longer here
L0dex: or it won't show up anyway
L0dex: rerunning lightmaps did not help
ShadowSpartan1: ummm
ShadowSpartan1: hmm
L0dex: do you have any idea at all what could be causing this?
ShadowSpartan1: when you open in sapien
ShadowSpartan1: what's it like
ShadowSpartan1: is teh scenery properly placed
ShadowSpartan1: as well as the AI encounters and shit
L0dex: uhm its all properly placed, same with ai firing positions, starting positions, etc
ShadowSpartan1: weird
L0dex: mhmm
ShadowSpartan1: so if u go back to original bsp, it's fine?
ShadowSpartan1: or have u even tried that
L0dex: yes it's fine then
ShadowSpartan1: wow
ShadowSpartan1: hmmm
ShadowSpartan1: I'm not sure tbqh
ShadowSpartan1 signed on at 23:27:30.
ShadowSpartan1: so it's all properly lighted and shit, which means u have the right ligthamsp tag
L0dex: yes indeed
ShadowSpartan1: idk really
ShadowSpartan1: makes non sense
ShadowSpartan1: no*
ShadowSpartan1: I would try asking on the forum

So as Shadow the wise suggested, I am here, pleading you all for help and/or ideas...

So, who knows how to solve this very odd and illogical problem :saddowns:

Redo the ai and see what happens?

The AI encounters and stuff are still there...
And making new encounters in this scenario still results in invisible/invincible characters.

No, thats stupid, becuase its not like there messed up if you think about it.

Is the BSP in the same exact place?

Yes it is. The only difference is that it's been portaled, that is all.

Have you tried compiling?

Yes, compiling left the same problems ingame as in sapien.
