Short answer
What does FS25 update 1.24.0.0 change for servers?Three points matter: vehicle configurations did not deduct money on multiplayer servers, which is fixed. The Lua function loadstring is disabled for security reasons. And getUniqueUserId() now raises a warning; the function will be removed in a later update.
What is in update 1.24.0.0
On 29 September 2026, GIANTS released update 1.24.0.0 for Farming Simulator 25. For server owners, three points matter above all; the rest concerns the game itself.
| Change | What it means for the server |
|---|---|
| Vehicle configurations did not deduct money on multiplayer servers — fixed | Affects your save directly: conversions cost what they are supposed to again |
Lua function loadstring disabled for security reasons | Mods that use it no longer work |
Warning for getUniqueUserId(), removal announced for a later update | Update the affected mods now, before they stop working entirely |
| New machines: Merlo EW 25.5-90, Škoda Fabia, SOLÀ AURA 2000, SOLÀ Velox 300/12 | No server work needed, they appear at the dealer after the update |
| Improved rain effects at high speed | Purely visual, no effect on the server |
Updates for three DLCs arrived the same day: Highlands Fishing Pack 1.5.0, Pumps n' Hoses Pack 1.1.0 and Straw Harvest Pack 1.2.0. If you use them on the server, update those too — otherwise the version will not match your players'.
Client and server need the same version
This is by far the most common cause of "I cannot get on any more" after an update. The simulator updates itself on the player's PC as soon as Steam or the launcher runs. The server does not necessarily do so at the same moment — and the two no longer match.
Checking takes seconds: the version is shown at the bottom of the game's main menu and in the server's web interface. Different numbers there, and you have found the cause.
Updating the server properly
Warn your players
An update in the middle of a session costs the progress made since the last save. Announce it briefly, let everyone save, then start.
Stop the server
Do not restart it — stop it. Only then is the savegame fully written.
Back up the savegame
Download the savegame1 folder via FTP, with the date in the name. That is your way back if a mod cannot cope with the update.
Apply the update
Trigger the update in the web interface. Even if it runs automatically, check the version number afterwards.
Match the DLC versions
If you use Highlands Fishing, Pumps n' Hoses or Straw Harvest, their versions on the server have to match as well.
Join alone and save
Test it yourself first, then invite the group. That way you notice problems before ten people ask in chat.
Mods after the update
Disabling loadstring is the change in this update most likely to break something. It affects script mods, not pure vehicle mods. The symptom: the server does not start, or throws Lua errors into the log while loading.
Disable all mods
If the server starts like that, a mod is responsible — not the update itself.
Switch them back on in groups
Roughly half at a time. That finds the culprit in a few restarts instead of twenty.
Look for an updated version
Most maintained mods were adapted after 29 September. If there is no new version, the only option is to leave it out for now.
The server log names the mod. Search for "Error" or "LUA" — the file name of the mod that triggered the line is almost always right in front of it.
When nothing works after the update
Stay calm first: the savegame is still there, and you have a backup. The order of investigation is always the same — compare versions, rule out mods, read the log. How that works in detail, and what the most common causes are, is covered in the guide FS25 server unreachable after an update.
What comes next
The Beans & Alpacas Expansion releases on 27 October 2026. If you want to prepare your server for it without rushing, the steps are in the guide Beans & Alpacas: preparing your FS25 server. Do the mod review above at the same time — it applies to both.
