not updating a2b and b9s update?

there are also some extra spaces on ssloth and skaterhax pages

[TophattedWasTaken]

have we confirmed the issue occurs with updating b9s and atob? this was definitely intentional and I for sure did not forget they existed

I can fix the spaces when I’m next available if someone doesn’t get to that first

I mean I doubt it actually happens there but I figured "we're standardizing it why not cover our ass and just standardize all the way"
