When someone tickle you from another chat, you get the tickle but it doesn't load the info of that user. It doesn't load their names, glows, photos, etc. If you click on their names, it will not load as well. Sometimes it just shows their ID number, but still doesn't load the info. When you hover the place where should be the person's photo, it shows the (kiss#gmback2#b2b2b2) smiley.
If the other user is on HTML5, the problems persists. However, if the person is clicking on you for the first time on the chat they're at, it counts as a double tickle.
* Step 2: Wait or ask someone to tickle you.
