"Format text" blueprint node causes freeze on compile

This is a freeze-on-compile issue I’ve been having migrating my working 4.10.4 project to any future version through the current 4.12.2. I have narrowed it down to the “format text” blueprint node. Attached is a video demonstrating the issue, and a very stripped-down version of my project that demonstrates the issue. Check it out:

Some PC specs: Windows 8.1, i7-4930K, GTX Titan original, 32GB RAM.
