Found an interesting bug: When a player logs into the site, he enters his login (in my case, it's The Uzoryz). The login is case insensitive, I can login as “the uzoryz”, “The Uzoryz” or “THE UZORYZ”, but it will work, there is no case sensitivity. But the trigger action “Set string-value of variable ‘A’ to the login name of player-initiator” is case-sensitive, not only that, it takes not the login of the player, but the text that he entered when logging in the site.
Thus, triggers that continue actions depending on proper login of the player wont work if the person does log without capitals or something.
