It does look alittle stretched there doesn't it
Only problem with fixing that is that the texture for it is hidden somewhere in the original sim's data folder, containing alittle over 4000 different textures that nearly all are named in Czech.
And even if I can find it I can't easily replace it as the whole texture folder is combined into one 200mb data.pbo file, so to change that single texture I'd have to replace the whole .pbo file.
