Any bug related to gmhl2e1_citadel_03 will be Unfixable

because i tried editing the map itself, and i cannot compile it whatsoever
i will eventually attempt (if god knows i am still alive, and have time) to try actually making a custom edit, instead of a CHEAP-MODIFIED edit of it done with EntSpy...

idk if is named urban flight, because i think flight is a plane, or im incorrect, i dont know if its other word, i say that because when i played hl2 ep1 in spanish it appeared as, exodo, idk is flight is exodo

It is correct, the chapter in Episode One is named "Urban Flight"

gmhl2e1_citadel_00
admin cleanup breaks the beginning ( intro disabled? )

I have found the following bugs:
Alyx repeatedly says variations of "Take the Gravity Gun" whenever she's not saying any scripted dialogue in the first map, even after doing so
You die on the van's trip through the Citadel in the first map
Alyx is duplicated at the very start of the first few Citadel maps
Alyx clips into the wall of the train car when the train wreck in c17_00 happens (it's also nearly impossible to jump up to the car's exit hatch after you free Alyx, requiring noclip)
The wrong texture is overridden on Barney: one of his eye textures gets his Episode 2 face texture instead of his face texture
Alyx gets on the train at the end without waiting for the player to first, requiring them to climb on top of the train to get on the platform as Alyx blocks them from doing so the normal way

gmhl2e1_citadel_03 can't edited? is a hardcored?

It's not hard-coded, has too much brush work for Hammer to compile, or something of that sort.

in the citadel there are some error models

Can you provide examples?

idk if counts as a bug but chapter Exit 17 after the 2nd civilian the APC shows up afterwards wont register any damage even with custom or HL2 weapons so hardlocks any progress thankfully had a jazznauts add on let me activate triggers.

BUG REPORT:the voice lines are not in the maps its just not there and i dont know why

Stupid i got error texture and combine too got error texture what do i need to fix?
