The way splints used to work was changed back in August, and it's probably best to keep them as they are now. Will however look into the timer not resetting on death @Locksmith/Jack Locks
Say you die at projex, you can still go do your job anywhere else as far as NLR goes. By disallowing them from responding to the same shootout they would still be locked out of the same area as an NLR zone, seeing as shootouts span over a lot of area so they should not go near anyways
Increasing NLR time is something I could actually get behind, rather than reducing cop slots. Scaling the timer on cops on duty or something similar might not be a terrible idea, to somewhat maintain the "difficulty" of dealing with cops while they are low in numbers.
With the same reasons as previous suggestions for this was denied. This also leans both ways, with low amounts of cops on duty, it is very hard to defend your property alone or with a friend or two. Raiding solo with a full server should be difficult
