Well .. it worked, sorta .
I was able to unblock the boarder patrol units, and the ATF Command Center. Unfortunately, I noticed neither unit has sirens their "mute" it seems, and there are no boarder patrol police officers available to staff the car. Do I need to add something else back, or is it just my end messing up?
I dont know exactly what you mean in regards to "mute." I mean I understand the definition of the word, but dont get the exact problem. None the less I am no longer going to offer support for units that I disabled. All I can say is I have not altered the disabled units in anyway other then perhaps lighting. So there should not be any problems.
Also, I have three other issues. I noticed I have 2 mass causality units, it's not an issue just thought I'd throw that out there. The battalion cars, and the ems cars are messed up too. One battalion cheif's car says idtooltipBC2 (I'm guessing because we have 2 spawning now?) The same goes for the dodge charger ems car it says idtooltipems2. I tired to see if I can fix this but I'm not that smart in that area and I kept crashing the game. I know it has to do with unit info thats about it.
Ok for the MCU, if you want to fix it, simple go into Units->Vehicles->LA Ambulance and delete one of the two MCU Folders.
As for the other units, pretty sure these were all fixed up in the patches provided. I would suggest you start applying the patches from the first post and see if it persists.
