CS:S - broken Event keyvalues (crashes in @Event) #536
Description
The 2026-09-16 update seems to have broken Event.variables KeyValues object
Event.variables.name works fine, but trying to access actual keyvalues data either returns default values or crashes:
@Event('player_death')
def _player_death(ev):
print(f"{ev.variables.name=}")
print(f"{ev.variables.get_int('userid')=}") # Crash
@Event('player_spawn')
def _player_spawn(ev):
print(f"{ev.variables.name=}")
print(f"{ev.variables.get_int('userid')=}") # returns default (0)As such, trying to access Event variables without Event's own getter method (get_int, get_sting etc) will lead to either crashes or KeyErrors:
@Event('player_death')
def _player_death(ev):
ev['userid'] # CrashThe workaround is using Event's own getter methods:
@Event('player_death')
def _player_death(ev):
ev.get_int('userid') # Works

This issue seems to occur only on the CS:S x86 architecture.
While this specific issue is due to an unknown member variable being added to KeyValues, it is unclear whether other changes from TF2 have been backported to CS:S.
I've added a fix for the Windows version, so if you're able to test it, please do so.

Well, it does. However, it doesn't seem to be an addition in this update, so it probably won't have any impact.

hl2sdk has been fixed, so #537 should resolve the issue. If you're able to compile it, please do so.

Here is the Compiled CSS Build including Windows and Linux binaries with the #537 fix, built against the latest SDK.
Also it includes my #535 updated data
