Toxin Damage is coming with burn damage

[Wilber456]

This Recent round I noticed that when I cauterized my bleeding with a Welder it instantly sent me to Critical and delt 80 or so Toxin Damage on the spot as well as 15 Burn damage and 20 Brute Damage, I tried it again later in the round with full Health to see if It was just a coincidence but it happened again, When I used a Health Scanner It read 80 Toxin damage and 15 Burn/20 Brute.
