Invisible blocks ??

[Epitaxis]

Hope this is the right place to post.

Hoping someone can help. We are running a FTB-Unleashed server.
A user was using microblocks as floors and ceiling tiles.
When he logged back in after 30mins or so, the blocks had disappeared.
He is able to walk through the space but is unable to place new blocks in their place.

Any suggestions on how to remove these blocks ??

Cheers

I think it is caused by bug in microblocks. I believe it has been fixed or it is being worked on.
