No problem
And wow you just solved one of my longest issues!! Lmao.
With several custom maps, I kept seeing those open spots (though not too often).. whilst others did not.
Now a simple vid_restart didn't work.. and I just tested several other options but those didn't affect it either.
Now my r_subdivisions (Curve Detail) was set to Highest in the in-game options.. yet when I changed it to lower, everything was fixed! BUT, changing them back to Highest, it was still fixed.. which was extremely weird.
Then I checked my config.. and my r_subdivisions was set to 1, whilst 3 is the in-game Highest. But MOHAA has 2 higher options (values 2 & 1), but they weren't added into the in-game option menu.. and now I know why.. xD
Here I was thinking that it would improve my game, but it added additional bugs lol.
So all is fine now! No need to fix anything in those tunnels ^^
About the bazooka guy, I'll try it again soon.. he didn't do anything for me because I wasn't in the 'arena'. Even when I returned to it, he didn't trigger for me at all.. so I was out of bounds during the trigger probably. So I'll try again later.
Not sure about the bot shouts.. I'll check that right away as well when I'm retrying the mission.
