Was attempting to place 2-pixel-wide panels onto a series of power cables from the Powah mod. The placed panels were invisible. Attempting to place down bits on proper block surfaces also rendered them invisible. I attempted to log out then back in to see if it would fix it. It kept me from logging into my world at all unless I disabled the mod itself.
