New launcher, patch download progress

Hello Riot and its community,

I'm here to send a feedback about bug noticed in new launcher. When downloading/installing new patch it is possible to get negative value for bytes downloaded resulting in bad time estimation as well. This bug isn't reproduced every time ( I know this because friends didn't have the same bug on same patch download ). I am attaching screenshot of it for better understanding.

Best regards, Summoner LeMilanche.
