I used the event on a t3 char. becose i dint see that im geting onle t1 and t2 mats cann i get the event on a nother character?
Maxbe set the event so you cant use it on a t3 character?
nope, you cannot. Sadly. Welcome in club 
Well tat is a bad game design 
Good that i got 3xt3 chars and 3t2 so not taht big of a deal but still stupid. Its not mationing big rewards for leveling. And not blovked with a doble klick for t3 chars so you dont use it for nothing.
Brother good luck
