Cant confirm this bug, all light working for me but there is BUG that if you are alone in vehicle, and turn on lights and switch seats then the lights turn off by itself (you can see lights on vehicle but it does not illuminate the surroundings)

can confirmed, people are just tossed around squads

well i just tested it again with newest exp update and the bug is still there BUT it only work in two checkpoints: one next to Military Coastal Base Chotain and one in Entre Duex
its very minor bug so there is no point in bothering you with fixing it, but maybe understanding the existence of this bug may be useful in the future, i dont know.

cant you just after capturing the base dismantle the sands and kill the guy inside ? you can always climb up and shoot through the roof
