CS 1.6 server crashes when loading CSGO-style custom maps (default maps work fine)

[hifuries-spec]

Hello everyone,

I’m having a crash issue on Counter-Strike 1.6 related to CSGO-style custom maps, not default maps.

Important clarification

All default CS 1.6 maps (like de_dust2, de_inferno, etc.) load and run without any problems.
The server and client are stable.

The problem occurs only when loading CSGO-style / CSS-converted custom maps that are supposedly adapted for CS 1.6.

The issue

When the server tries to load one of these maps, it crashes during map loading (before players can join).
This happens consistently with every CSGO-style map I tested.

Tested maps that crash the server

All downloaded from GameBanana:

dust2finalfinal.zip

css_assault2.rar

de_dust2_winter16_cs16.zip

de_beishan.7z

de_dust2_2020_b97ad.zip

de_dust2_2020_csdm.zip

de_dust2_xmas_2.zip

css_dust2_go_21983.rar

fy_icy.rar

css_dust2_remake.rar

(Default CS 1.6 maps work perfectly — only these custom maps crash.)

What I suspect

These maps may be:

Compiled for CSS / CSGO BSP versions

Using unsupported entities

Using models / textures / shaders not compatible with CS 1.6

Or the maps are labeled as “CS 1.6” but are not fully compatible

My questions

How can I verify if a CSGO-style map is truly compatible with CS 1.6?

Is there a reliable way to check:

BSP version

Entity limits

Engine compatibility

Are there known limitations when running CSGO/CSS remakes on GoldSrc?

Is there a recommended source or guideline for CS 1.6–safe CSGO-style maps?

If needed, I can provide:

Crash logs

Server configuration

Exact addon/mod details

Any insight would be appreciated.
Thanks!

Hello, post your crash logs and what is the server printing in the server console when a crash occurs.

hat’s very interesting, but it worked—thank you. By the way, I have a question. I’m using SQLite instead of MySQL, but when I shut down and restart the server, the existing skins get reset. However, if I enter the wrong password, it says it’s incorrect. The interesting part is this: if it says the password is wrong, that means it’s saving records to the database—so why are the skins disappearing? Or do I need to use MySQL instead?
