If you rebind the F1/F2/F3 keys to something else so you could pick a loadout, they don’t always work.
In the beginning of the rounds you can typically use whatever key you set (In my case I set Numpad 1/2/3) but it seems that when i try to use them after I die/tap out, it reverts back to F1/F2/F3 and there’s nothing I can do about it.
Hoping this is something not too hard to fix 
I made an earlier topic on this but didn’t read the rules on how to title prior, my bad.
