I thought I should show you the portion of the config file that I am referring to. When I change the line for the number of players who need to be online for 1 tank to spawn, anything less than 2 gives that call hook failure.
"default": {
"Tank Route - Road IDs (Random, if more than one)": [],
"Tank Route - Use all default roads": false,
"Tank Route - Use longest path": true,
"Tank Route - Remove first and last checkpoints": 0,
"Spawns - Announce Spawn": true,
"Spawns - Announce Kill": true,
"Spawns - Respawn Time (in seconds)": 900,
"Spawns - Respawn Time Randomize Value (goes +value and -value from option above)": 120,
"Spawns - Min. Online Players For Each Tank Amount (Amount Of Tanks: Amount Of Players)": {
"1": 2,
"2": 8
},
"Spawns - Chance": {
"Hard": 2,
"Normal": 5
}
},
