War of Assassins - Ordos Mission 8 is different from YouTube playthroughs

[Abbat]

Hello everyone.

I am playing War of Assassins using Gruntmods Dune 2000 (Mission Launcher).

I have a problem with Ordos Mission 8.

In my version of the mission I cannot build:
- Starport
- Rocket Turrets
- Palace
- IX Research Center

I also cannot build upgraded turrets that are available in the YouTube playthroughs.

However, I found several YouTube playthroughs of the exact same campaign and the exact same mission where all of these are available.

Examples:
https://www.youtube.com/watch?v=olbQapVl8hU
https://www.youtube.com/watch?v=-hW_-GP-N1s

I already checked my installation, opened D2K_O8.MIS and D2K_O8.MAP in the D2K Map & Mission Editor, and compared the mission settings. Everything seems normal, but my mission is clearly different.

Could someone please tell me:

1. Which version of War of Assassins are those YouTube videos using?
2. Is there a newer or older version of the campaign?
3. Could someone share the correct campaign or the correct D2K_O8.MIS file?

Thank you very much!
