invalid decoded tile count

[nexovec]

Hi, this basic code triggers a panic

	tiledMap, err := tiled.LoadFile("assets/platform.tmx")
	if err != nil {
		panic(err)
	}
	slog.Debug("tiled level", "tiles", tiledMap.Layers[0].Tiles)

What could be happening?

Please provide either sample file that would allow to reproduce the problem or at least stack trance and exact panic message

I forgot the repo is private(I can see some of my commits that link this issue here). Sorry for the delay. Here is the stack trace. I can give you a repro if needed.

Minimal reproduction is now available in bugs/failing_load. You should be getting this when you run it:

go run .
panic: tiled: invalid decoded tile count

goroutine 1 [running]:
main.main()
	/home/nexo/src/go-tiled/bugs/failing_load/main.go:13 +0x146
