SAR Crashed Portal: Prelude

[MikeyBot3000]

The plugin works fine when I'm trying to load it with standard Portal or Portal 2 but when I try to load it with Portal: Prelude the game crashes. I removed all of the commands relating to SAR in the autoexec.cfg folder like "bind k 'incrementvar sar_sr_hud 0 1 1; incrementvar sar_hud_demo 0 1 1'" and "sar_speedrun_time_pauses 0". The mod worked perfectly fine with the plugin before so I don't know what I did before to make the two not compatible with each other.

Edit: I feel like it should be mentioned that I'm using the Mod SteamPipe engine to play the game instead of Source Unpack

Edit 2: I just tested it and SAR works perfectly fine with Portal: Unity (also using the Mod SteamPipe engine)

Edit 3: SAR works fine with the Source Unpack 2.3 engine with the base game and it works fine
