I am working on a huge map where some of the Chisels and Bits blocks are being updated to Little Tiles', and I've been noticing these rendering glitches as the one shown bellow, I don't know it it's a C&B's error, Chisel's (Other building mod) or LT's...

There is also errors with huge chunks of blocks disapearing after a chunk is updated.

Update to the latest version and disable Render Regions.

I will close this issue for now. If it still happens just let me know here.
