Hi,
I was playing one of the contests from Opentrains today, but system was very unreliable:
I saw a lot of times result "Check failed"
When I sent the same solution, but different languages, I got a few times "Check failed" and once "AC"
The same solution on different attempts get PE18, PE34, PE36 etc.
When I was trying to submit solution, I got a lot of times "Disk write error (disk full?)" message, and my solution wasn't submitted.
I believe there are problems with Opentrains. Can someone who has access check and fix it?
Thanks!
