Hey, this is no doubt one of the worst feelings in League. If you're able, can you send in a support ticket with your logs attached. You can just zip up the whole folder I'll make sure they get to the right people.

Issues like this are hard to track down, and logging won't always tell us what happened, but any little piece of information helps.

Best info to provide: * this video * pc specs * log folder zipped * network provider info and if you're wired or wirelessly connected

i'll just tell you what happened in my case (don't want to make a ticket)

1. client was very slow.
2. i traded with friend n1.
3. shortly after or at about the same time friend n5 traded with me
4. i declined his trade since i had traded with friend n1.
5. friend n5 tried to trade with friend n1, however friend n1 was unable to accept. nothing showed on his screen, and he was locked in doing anything. he couldn't choose his summoner spells either.

that's all i got, hope you guys will manage to fix it.

Thanks for the details. Let's see if we can reproduce with those instructions.
