Describe the bug
When actual Mushroom Blocks are placed, they randomly set connected mushroom blocks to either a texture with "UNUSED MUSH ROOM" written on it, or a TARDIS texture.
Same issue (I believe) as #125
I originally commented there because I assumed it was because we'd added the TARDIS plugin after the building was built and was seeking more details on how to trigger the provided fix, but placing more blocks gives the same behaviour so it's possible a regression.

To Reproduce
Steps to reproduce the behaviour:

1. Install TARDIS Plugin
2. Enable Resource Pack
3. Place multiple (5+) connected Mushroom related blocks in creative mode
4. See erroneous textures

Blocks should be normal after either:

• Leaving and rejoining the world/server, or
• Placing a non-mushroom block next to the affected blocks

The TARDIS plugin cancels the mushroom block update on the server, but the Minecraft client can still show a TARDIS mushroom texture until another block update occurs.

Thanks, so I've done a bit of testing.

Any mushroom block placed before the TARDIS plugin was added does not respond to block updates.
Similarly any block placed using world edit, even after the TARDIS plugin is added, does not respond to block updates.
However, once the block has been re-placed by hand, it does respond to block updates as per your video above.

However, all it takes is for another mushroom block to be placed (or replaced if one is accidentally removed) and every attached mushroom block is broken again, eg this:

turns into this:

My member has built a lovely little mushroom house:

Telling him he has to manually replace all those mushroom blocks and then go and trigger a block update on all of them to fix them, and then hope nothing re-triggers the mushroom block update that will break them again, is more mean than I'd prefer to be.

Can you think of any better way we could fix it?
I'm happy to put in extra work setting up a command block he can use to run a WE command to fix it or something, I just don't want his only option to be manually clicking blocks one by one all the time.

Could possibly add a quick command to replace exiting mushroom blocks similar to /replacenear that will work... but won't get time until tomorrow

That would be great actually, thanks!

Wonderful, you're a scholar and a gentleman, thank you!

I'll chuck it on the server right now and give it a go!

Works like a charm!
Even works on blocks that would otherwise have had to be re-placed by hand :)

Many thanks for your hard work as always!
