You have multiple grfs with the same grfid. Change the grfid in your NFO, or get rid of the older versions of the grf.

Hmm, I don't know what I'm doing wrong. It just doesn't list anything now. I deleted the 2 other tar files. There's only patch.tar in the folder. Is this what I should have done?

[PikkaBird]

Why do you have .tar files?

[Samu]

I'm puzzled, I must be doing something so trivial to you and I just don't get it. Forgive me.

[Yexo]

You don't need to put the grf in a tar file for openttd to read it. In fact tars are only used by the online content system to a readme/licence file can be packed.

[Samu]

Ah... I understand now.

However, it still doesn't work. There must be a problem in the grf file itself, it still not listed. I tried putting the other grf files back in and they are being listed. It's just this one. t.t
