FTB Beyond strange visual glitch

This glitch was only visual and happened after i server restart, it was gone when i relogged but i still wanted to share what i saw. My base is just below the surface so when i logged on and looked up i didn't expect to see these solar panels:


Then i saw a gap in my wall and was amazed when i looked out of it:


After this i climbed my way through the many solar panels to the top. When other people visited they said it looked like i was flying because i was standing on solar panels which were invisible to them. Here are the rest of the screenshots:

 

If you've used the image button in the formatting section to place in your images I suggest just dragging the images from imgur onto the post; or creating an album and posting that link. Because as of right now, the images are broken.

 

Are they broken now? I can see them now that i have edited them.

 

Uhhhhh i am not an expert but try reinstalling the pack?

 

There was no need, luckily for me it was only a visual glitch so when i re-logged it all looked fine again.

 

heh, this looks so strange i still don't know what i am looking at, or believe its true

 

The issue here was a classic Client/Server sync issue.
This happens mostly when teleporting between dimensions.
Essentially, the server somehow failed to properly tell the client about the surrounding area, and the client tried to "fill in the blanks", resulting in various "ghost blocks" filling the area.
