maybe bug after league lobby match ended

[mapleray]

dota2 version: dota2==1.1.0

After calling create_practice_lobby with leagueid=xxxx parammeter and launching it, I can find the match in dotabuff league page, see as below:

But when the match was ended, dotabuff showed that the match still was living, and maybe several hours passed, the match disappeared and could not find anymore.

Before TI10 it's ok to use bot to create league lobby, but after TI10's updates, it doesn't work anymore.

Can someone help?
