I have day_fin2 playing on my server and have it re-directing to Skillz FTP. People are joining without problems. Could be the server cache? I'm not very good with the server stuff. You need a PhD just to setup a server and troubleshoot it if something goes wrong.
Don't know what to tell you about the thunder, you mentioned you had a couch sized stereo haha, that's pretty overkill man, you gonna blow your ears out. I asked people playing on my server about the sound and they all said it wasn't too loud.
I actually reduced the thunder sounds as well after you mentioned they were too loud. Any lower, it won't sound like thunder anymore.
i must have downloaded the map between overwrites, i downloaded it again it loads correctly.
the animal sounds are tolerable now but the thunder is still incredibly loud on my end. but as i mentioned, my system is 2.0, plain stereo, it is not a surround sound system.
and though my system is very powerful and accurate, the volume of my speakers isn't the issue. i still find the volume of the thunder to be disproportionally loud in the audio mix, to the point where all other sounds are almost completely drowned out of the mix by the thunder. and it still seems to happen a bit too frequently imo, like every ten seconds may be a bit much, even if it wasn't the dominant sound in the mix but you may have no control over that.
i checked it out in my headphones too, which are also standard 2.0 stereo, and it's the same story, the thunder is literally, painfully loud when all the other sounds are at a comfortable volume.
it also doesn't help that it's not the best recording of thunder I've ever heard, the frequencies are very heavy in lower mid-range with a high and low frequency cut-off but that's beside the point.
i guess i'll have to stick to the day map even though i prefer the look of the night map. i wouldn't lie to you, it's that bad.
