Aliens TC E2M5: Bugged secrets?

[guineu]

First post so sorry if this is not the place to ask.

I've been playing Aliens TC and most secrets are not even hidden, usually just a random room. But then there's map E2M5 which has 4 secrets and I couldn't find any of them. The level has a secret exit to level E2M9, but nothing in the process of accessing that exit triggered a secret.

I was really curious so I used automap cheats. Tried both 'idbeholda' and 'iddt'x2 but the secrets still didn't show up on map, while trying the same on other levels would show the secrets correctly. I also used 'idclip' and (I think) I visited every room in the map.

Then I tried searching for a walkthrough or guide on google but all I could find was the wiki mentioning the secret sectors: https://doomwiki.org/wiki/E2M5:_Atmospheric_Processor_(Aliens_TC)

Secrets
(sector 233)
(sector 293)
(sector 301)
(sector 316)

I couldn't find a way to make GZDoom display the current sector position and before installing a map editor just for this I decided I could try asking. So, anyone knows if those secrets are obtainable or are they maybe bugged?

There're no secret sectors in that map. Also there're no sectors with indexes mentioned in the wiki. I guess all that stuff was moved to the E3M1 after E2M5 became too big. It also seems like E2M5's SECTORS lump still has data about removed sectors, but they're actually not there.

Oh I read about the map being split on the wiki but I didn't realize that would be the explanation.

Thanks! Problem solved.
