Upgrading HB tier

oh, much thanks, kind of missed it! Cheers to you man <3

is this real? so even if the bundle ends it is possible? that's awesome

I think the ability to do that after the bundle expires was removed back in October last year (?). Had a bundle I wanted to increase, but couldn't after a week or so. I think they also removed the FAQs about it. Haven't tried to do that since, so I'm not completely sure.

Oh, looks like they shortened the period to 7 days:

This option will be available throughout the bundle sale period as well as for 7 days after the bundle has closed.
