I created a problem in Polygon. Everything worked fine when I built packages for revision 1 and 2. After some changing (add a test, change the problem statement,...), when I built package for revision 3, the package was created ok, but the problem in codeforces didn't update and showed that 'no problem was found in this url'.

I have tried many times to add this problem to contest again but it only showed that 'could not download problem descriptor [...]', even if I have set permission for codeforces to read the problem (and notice that the packages for revision 1 and 2 worked fine).

Is it a bug? Can you give me some ways to fix this (but don't tell me to create a new problem :)))

If you want more information (problem URL,...), you can talk with me.

Thanks!
