I have checked both console and server console for why this is not working, but vehicles are not spawning, no error message, not even the hl2 vehicles will spawn.
Status:
rp_evocity2_v1p(i think its v1p) on a cider gamemode running latest version of gmod and srcds(dedicated non steam version).
Note: even after i set the sbox_maxvehicles to 5, it still will not let me spawn them.
