Purple/Black Textures-Random Block ID Changes

Blocks within the world have been showing "black and purple" checkerboard textures - the following blocks have been affected:

Stone and Grass blocks.

This appears to be occurring to random blocks/random selections of blocks - I have checked the following versions and they all appear to be affected:

Version 14w19a, 14w18b, 14w17a, 14w11b

Version 1.7.9 is NOT affected.

The blocks themselves when analysed in MCEdit show the following ID's: 1:9 (Stone blocks which were affected) and 2:8 (grass blocks affected) - they also show as being "null" models and flash up as "Round trip different" when the F3 console is open and the blocks are looked at.

Middle-clicking on the blocks produces an ordinary block which if used to replace the glitched blocks makes them appear "normal" again - the blocks are also easily changed through MCedit by replacing the block ID's with normal, expected block ID's (e.g. replacing 1:9 blocks with 1:0 blocks resolves the issue.)

.olding the .Minecraft folder in the "Roaming" folder has had no effect and the issue is experienced with both the normal resource pack along with additional resource packs that are added.

The map has also been updated from an earlier version - the map itself has been around since before the 1.7 update - the areas experiencing the issues were also loaded in before the 1.7 update. (e.g. the map has been periodically moved from update to update as the new snapshots and versions have been released.)

Did this happen when generating a new world, or updating from an older one?

Updating from an older version - I've been more or less making jumps up from each version prior so 14w18b to 14w19a etc.

This seems to only have occurred in areas I haven't "visited" recently and only seems to occur with surface blocks as far as I can see.

I'll add the above into the report though for reference.

Could be related to MC-50998

Sounds like it is related to: MC-50998

The grass and stone blocks still retained their "normal" features e.g. sounded like I was walking across grass etc.

As far as I could see the only thing wrong with the blocks is the ID value - although I have no clue as to why they seemed to "glitch" and change.

But yeah, seems to be related.

Preben Gjelsvik

Yeah, the metadata seems like it has changed for some reason, the reason they they look "glitched" is because they don't have a texture.

Those blocks have incorrect data values.
Invalid.

Plus, probably a duplicate of MC-50998

Invalid data value, there is no Stone:9
