Memory leak / Unknown Command (?) on KDE neon playing vanilla half-life 1

[robogaming]

I'm not sure why, but when playing half-life (with the files copied directly from steam, I was using this engine because it performs and looks a lot better on my PC) after about 45 minutes it crashes with a different memory related error and an "Unknown command: VMod Enable" each time. Before crashing it exits to the main menu and when trying to load up the last save the entire game crashes.

First crash:

• Unknown command: VModEnable
• Segmentation fault

Second Crash:

• Unknown command: VModEnable
• Mem_Free: not allocated or double freed (free at common/soundlib/snd_main.c:139)
• cmalloc(): smallbin double linked list corrupted double free or corruption (!prev)
• Aborted

Third Crash:

• Unknown command: VModEnable
• free(): invalid pointer
• Aborted

To 1: They don't have a file for my architechture (x86_64), but I'll try to run the x86 To 2: Those are basically it, the only thing that comes before is stuff that happens on every load
