So, I was trying two "mods" a few minutes ago.
Link9rly's Vanilla SA and SA:MP Addon
Both of them caused my game to freeze instantly after I chose a spawn option.
The thing is that this only causes the game to freeze in Argonath.
While I tried the same things on 3-4 other servers but it works completely fine, no problems at all.
What actually causes this to happen in Argonath?
Can it be fixed?
