Not sure what you mean by game mode but I think I can guess.
I have never played any other GoldenEye game other than the release of about a week ago. That is, GoldenEye_Source_v5.0_full.exe. I had never even heard of the game until this August. Glad I did.
Other than that, it is just me against bots with "Mangley's Sneaky Set" as weapons choice and any map. For a short time, "Mangley's Sneaky Set" would not even load and I would get the hl2.exe windows dialog box "Not Working" message. Now, for some reason it runs for maybe 15 seconds and then crashes, as shown in the JPEG photo. Even if I just stand in one place and do nothing, the crash still happens in the same amount of time. I thot maybe it was running over the weapons box in front of the character, which was knives, but it still crashed in the same amount of time, even if I never moved, at all, or went around the box and never engaged it. Not sure what is going on.
However, I just tested the game using a different "Scenario". It was crashing on on "DrNoArmor" as a scenario so just switched to "Arsenal" for about a minute. No crash in that short amount of time. Didn't run over any boxes, either tho. Switched back to "DrNoArmor" and the hl2.exe crash happened right on time, again. Seems the combo for the crash MIGHT have something to do with "DrNoArmor" as a scenario AND using "Mangley's Sneaky Set" as weapons. I didn't switch maps but I don't think they matter with the crash. Again, it is just me against bots.
I'm only running the client, so haven't run into any problems with server admin stuff, yet. :]
There is another bug I found with "Voice" in options, but I will put that in another post. It's probably not related.
Thanx for getting back so quick.
