First, thank you for investigating and fixing.
I installed candidate beta version to local.

Like you said, I confirmed script errors.
and I checked your modified source code with WinMerge diff tool.
(checked hl_weapons/weapon_hlxxxxx.as too.)

It seems "m_pPlayer" member doesn't work by specification change on weapons script in next version.
may be your code is correct and it seems no problem.
(I believe site admin repack and upload these files. so, I probably not doing anything (((( ﾟωﾟ) )

uboa_rampage is undergoing correction work. (maybe)

Nevermind, just had to download it again.

Why …? that's because for updating, fixing glitches, and adjusting game balance. (And at first release time, I uploaded as WIP map)

The problem of differing bsp is,
if my memory is correct, someone was asking same issue on official forums or Steam forums.
Search it later. you will understand that is specification and client need remove it to join.

Well if you wanna make a update of a already release map, at least change the name, this map became very popular at some point and a lot of people have this map dowloaded, you can't expect to all people that have the old version delete by hand the old .bsp file, because not everyone has such basic computer skills, just that.
I had no other way out than to delete pizza_ya_san1 from my servers, unfortunately, I personally love this maps and sequel. Thanks.

I know some mappers adopt revision style like a "pizza_ya_san1_v2.bsp". but I hate this style.
you'll better to change name or ripent if you don't like my style.
manage it as server admin, please. I don't want to manage up to there.

It's the best way to prevent this type of errors, well I'll see what I can do and save it using ripent.

It looks like missing a wad file.
Put "pizza_ya_san.wad" to svencoop_addon or svencoop_downloads folder.
This is a necessary file. do not delete this.

Read "Installing custom maps" article of here.
http://www.svencoop.com/manual/server-basic.html

Make sure file structure, and how to install custom maps.

Some players connecting to my server have the same issue, for some reason the main .wad doesn't download.

Was the WAD updated when the second map was released? That could be why some people are missing textures (they have an old version of the WAD and so they don't download the new one).

The wad file was included in bsp when first time released.
If using HTTP server for download, check server responses on log file please.
Response code, download path, byte size are correct? and so on.

I mean, this is trivial, but I felt like pointing out vinesauce is a group of twitch streamers, not strictly youtubers
