Hi Hhampuz. I am not a campaign participant. I know the new signature code will last for four weeks.
But, The new set of signatures doesn't show correctly on Mobile devices when placed in the Signature space. It's showing well in the OP. Sr. member, Hero/Legendary Signatures are showing broken on Mobile devices while other companies' signatures are fine. I checked on Multiple devices and different browsers. It's broken (As shown in the picture below). I tried rotating the device. Still same. It's showing fine on Computer. If you have participants using a mobile device, they may confirm if they want.
Cheers!
