Problem D of Codeforces Round #224 has incorrectly rendered samples for me. (Chrome on Mac). There are curly braces in the output for samples 2, 4, and 5. These are not in the actual data, they are just on the website.

Here is the second sample:

3 4
####
#>^{}#
####

The curly braces are not supposed to be there. I know there have since been updates to how samples are rendered (showing different backgrounds for adjacent test cases within the same sample, for example), so I suspect this may have broken in one of those updates.

Not sure where to post this, so thought I'd flag it here.
