BreakHitResult + FormatText node re-arranging = Internal Compiler Error

Repro Steps Video: UE4Editor Blueprint/Framework + Format Text node Bug - YouTube

Using a BreakHitResult and then changing the Format Text nodes and then compiling spits out some errors.
Restarting the engine solves this problem, but it’s obviously fairly annoying.

Note: This is just a fresh FPS Template. The extra nodes at the top are not connected anywhere.

Version: 4.6.1 and 4.7 built from Source ~8 days ago

Tried to reproduce this in an independent BP (as in, no break hit result and other stuff) but that didn’t do anything strange:

Hi Moter8,

Thank you for the report. I was easily able to reproduce this issue so I have created JIRA UE-6864 in our tracking software. Our developers will be investigating the issue.

The workaround, as you mentioned, is to restart the editor and the errors will disappear.
