I was at 1 HP and fighting spiders when I got it, could be that
for sure is that I don't know why but basically we had a similiar problems with door s we had to redo the entire door system so it works properly now
I have the same error when i died with 1 hp in the level after you shoot alien to get the key.
I guess I couldn' fix it on time
And I don't think anybody's intersted enough for me to fix it after the jam even if I know the issue
