So as imposter I've had multiple reagents go afk or stall before you can invade and will never progress the trial until you leave

Red barrels please put a timer on the start before we can invade as there are players who will just stall and never progress the game until you leave. Had a guy do it for over 20 minutes and other who were the same. I understand the feature and why we can't invade right away but there needs to be a failsafe for these players so they can't just afk till you leave so they get easy win and xp
