Faceit - unexpected EOF: demo stream ended unexpectedly

[maddenbjames]

Describe the bug
After parsing the entire demo, at the end of the parse it will show this error
failed to parse demo: unexpected EOF: demo stream ended unexpectedly (ErrUnexpectedEndOfDemo)

This has been happening a lot more as of late, and as far as I can tell almost exclusively with faceit demos.

To Reproduce
Demo page download
https://www.faceit.com/en/cs2/room/1-2304a144-2f75-4ab1-913d-2826bb857ae3

Run it on any parser, tested with our intricate one and also just a basic kill printer

Code:

func main() {
	f, err := os.Open("../demos/test.dem")
	if err != nil {
		log.Panic("failed to open demo file: ", err)
	}
	defer f.Close()

	p := dem.NewParser(f)
	defer p.Close()

	p.RegisterEventHandler(func(e events.Kill) {
		var hs string
		if e.IsHeadshot {
			hs = " (HS)"
		}
		var wallBang string
		if e.PenetratedObjects > 0 {
			wallBang = " (WB)"
		}
		fmt.Printf("%s <%v%s%s> %s\n", e.Killer, e.Weapon, hs, wallBang, e.Victim)
	})

	// Parse to end
	err = p.ParseToEnd()
	if err != nil {
		log.Panic("failed to parse demo: ", err)
	}
}

Expected behavior
It finishes the parse with no error. This error seems to happen either at the start of the demo or at the end of the demo parse.

Library version
v4.1.2

Maybe related to this? Just throwing info out there, our CS mod guy said this was added 2 days ago to the demo.proto
