Sure, I can do that. This is for Be A Pro, not Franchise. New saves don't change anything. The line changes were a little wonky since release (jumping off the ice and then back on immediately without any "bench view") but it's gotten much worse after the last update (sending me back on the ice after a few seconds with no stamina left, then benching me for half the period).
It kinda feels like you get X shifts in a period but because they're all back to back, that counter maxes out in a couple minutes so you get benched. Anyway, thanks! I'll try to capture the video today.
