Given there won't be a release this sub cycle it's unsurprising, and despite how much the discord sycophants might've been cheering for the fanfest, you'd expect there to be some portion of supporters who fall outside of the main rabble, from those not on the discord to those who just lurk, some of them almost certainly felt the fanfest was a fucking stupid waste of time... cancelling a sub wouldn't be reflected straight away, i think it likely that $600 drop is the silent portion voicing their displeasure/disinterest and/or saving their money until there's an actual update to sub for, and who can blame them?
