When placing down a block from Blockcraftery a message appears in chat saying "CCL Caught an exception rendering a block. See the log for info."
The block is then invisible.

Using a block on it makes the same message appear and changes nothing.

Log

Pretty sure this is fixed now. closing since it is extremely old and I haven't seen the issue in newer versions.

Could you test is this still occurs without better folliage?

It still happens

Still occurs for me on the latest 1.12.2 build, same log message in the chat.
