Crash Offsets


This page attempts to collate the offsets found in this thread into a single, searchable database.

The crash offsets are available as a JSON payload should you want to use them in automatic crash detection.

Finding Your Crash Offset

In order to get the offset from a crash:

  • Press Win + R, enter 'eventvwr.msc' and hit okay.
  • Go to Windows Logs, then Application Logs and search for your crash.
  • Under the 'general' tab, note the faulting module name (i.e.common.dll) and the fault offset(i.e. 0x000d21eb).

If you're using the event viewer for this a lot, you can use the following xml filter to only show errors generated by Freelancer.exe and flserver.exe:

<Query Id="0" Path="Application">
<Select Path="Application">*[System[(Level=2) and (EventID=1000)]] and *[EventData[Data and (Data='Freelancer.exe' or Data='flserver.exe')]]</Select>

content.dll12e10IrateRedKite2021-07-26T13:03:00.000ZRelates to a bad NPC costume (inconsistent gender choices according to IDA) in mBases.ini. This also occurred when attempting to load an NPC in a [BaseFaction] block that hadn't been defined as a [GF_NPC], so this crash likely just relates to a failure to load an NPC in general..
content.dll956e4IrateRedKite2023-03-13T11:44:00.000Znpc_ship in faction_prop.ini listed that does not exist. This offset has also been seen as 0x0013f932 in kernelbase.dll when launching flserver.exe with flhook.dll preloading files.

This occurred when ammo entries for loot were not defined in lootprops.ini. If a munition entry has 'requires_ammo = true', the ammo AND the gun both require a lootprops.ini entry. The server crash offset for this is 0xe06d7363 in kernelbase.dll
content.dll1833fIrateRedKite2024-01-11T14:01:09.000ZA mission trigger without a condition was invoked. If the trigger doesn't require a proper condition, it needs a `Cnd_True = no_params` line.
