F.A.Q.

# Will I get banned from GTA Online for playing SandM?

SandM is designed as a separate custom multiplayer experience. It keeps your base installation clean and uses cached server assets instead of replacing your original game files.

# Why could SandM need validation?

SandM may use validation systems to protect communities, reduce abuse, and keep servers safe. SandM does not provide game files.

# Will updates require me to redo my server code?

The goal is to keep resources compatible whenever possible. Major runtime changes will be documented with migration notes and clear developer guidance.

# My SandM client crashes, what should I do?

Post your logs and crash details on the forums or contact support. Include your system specs, server name, and the steps that caused the issue.

# What does the M stand for?

Modding, multiplayer, and managed communities. SandM is built for custom GTA worlds, creators, and server owners.
