With our server being full a lot of the time I know it's frustrating not to have a reserved slot. Currently their is a bug not causing the reserved slot system to work. The developers were made aware of this issue and responded to it on 6/1/2017. The information below is how the system is supposed to work. As soon as the bug is fix we will be adding reserved slots to our servers. https://forums.tripwireinteractive....-support/2294193-reserve-slots-question/page2
