After going to red flashing and using Epi and morphine.
After the meds work out the character limp is not bad and is able to run at full speed.
Here is a clip of Paul, TRMZ, his stream today. I will try to see if I can reproduce this
Paul stated he had this multiple times after using meds
(edit: I just realized theres a good chance you allready know this and thats why Epi doesnt work in Experimental, buyt hey ho, here ya go)
