I'm following this mod actually since 2010 and I'm very impressed by this modification. I recently installed the latest build, did all available updated but encountered one minor bug at the very beginning of the game:
When attending the mission "Conduct Unbecoming", the safe house icon at the barracks kinda "freezes" on radar. I actually turned on my PS2 to check if the original game behaves like this, but it doesn't. There it vanishes correctly when attending the mission. Furthermore, this "bug" popped up every time I reached that point in the game, so it's no "one-time"-thing.
EDIT: I actually could reproduce this while on the mission "Cholo Victory". When you are told to chase that Cholo car, suddenly the safe icon turns up on radar:
here (while Conduct Unbecoming) here (while Cholo Victory)
Another issue was the "map label bug" (I really don't know how to title this, actually!)
Watching the full screen ingame map (NOT the radar!), the area names are "cut off" in actually every resolution. I tried it in 1440x900 as well as in 640x480, the issue stays the same.
