Repair instructions
There is a very serious bug in zombie riot v1.9.1b. The weapon may disappear suddenly when you use it, or it may disappear when switching between levels.
Thunder404 has produced a fixed version. Although most of the bugs in v1.9.1b have been fixed, But Thunder404 has not fixed the problem of weapons disappearing.
Fixed by 404 version:

Fix by Trace
I modified the plug-in based on the fix_by_404 version, he can run perfectly on the latest version[2020/5/23] of CS: S.
Plugin Description:
What this plugin does is change the objective of any map into one thing: the annhilation of every zombie in sight. The zombies are basically bots with a new model, modified health, and modified speed. There are different levels of play, or "days." Level options are defined in levels.txt, there you can set the amount of zombies the humans must kill, and how much extra HP each zombie will receive. If the humans manage to kill the zombies required for the round, the game will advance to the next level. If the humans are defeated then it will backtrack a day. A lot of the features are similar to Zombie:Reloaded, because most of the plugin was copy pasted from it.
