HorzLabelFormatting error crashed a match

The game just crashed on me on a perfectly normal map, match and situation. I'll add the logs in a bit. The CEGUI.log file has this in the very end:

11/08/2014 19:28:54 (Error) There is no Property named 'HorzLabelFormatting' available in the set.
11/08/2014 19:28:54 (Error) Exception: There is no Property named 'HorzLabelFormatting' available in the set.

A misspelling? Should it be "HorizLabelFormatting" instead somewhere in the code?

I was playing against papapump1228. The match isn't shown on the Recent Matches tab in the MP lobby. I guess it crashed for him, too. The result doesn't show on the team I played with, either, the team is still 1-0 even though this was its second match.

I tried a leap with a Wardancer. The leap failed and then the game crashed. Here are the logs.
