If you had textures that are not a power of 2 sized the ddnet client would give you a warning
But happened to me, when messing around with forest type Assets and all were correct according to the client. Interestingly I was only able to recreate it in a certain way ever since, so I believe that a certain amount of memory data is being corrupted and can be the result of quad miss-positioning / miss-coloring (edited)
