From 87cfe5b1da758c52df3c2d578937d86f4db79a8e Mon Sep 17 00:00:00 2001 From: Morph <39850852+Morph1984@users.noreply.github.com> Date: Wed, 10 Mar 2021 11:15:05 -0500 Subject: time: Fix CalculateSpanBetween implementation CalculateSpanBetween passes in the ClockSnapshots through 2 input buffers and not as raw arguments. Fix this by reading the 2 input buffers instead of popping raw arguments. Partially fixes Super Smash Bros.
