Rare bug , but real , tank spawned 2-3 times on a map versus ...
I look the log file but not error on ... No idea reason....
MAJ : I think look the problem ! ^^
With defaults setup enabled in the pluggin , map on map , if he is active , possibly tank spawned 2-3 times on a map versus (bug) , but if he is OFF (keep setup custom) , apparently bug not appear (?).
